Hi All

Currently have my clones well rooted(6" roots) in diy aerocloner but not sure if my ec is too high/low. My PH is stable at 5.8 and ec 0.7.

Using Ionic grow but also have formulex which i have not used.

The roots are flying but leaf growth is poor. I will be transplanting them soon into a bubbler, do i keep same levels ?

Cheers

I grow in coco using Ionic, at 3 weeks I have usually planted my clone into a 3 inch cube of rockwool with an ec of 15 and ph of 5.8, and they love it. Another week of that and into the coco, then an ec of 15 all through the grow.

Fraid I have no experiance of bubblers but it can't be much different and anyway I find Ionic very forgiving if you overdo it.

If you take a look at growth technologies website it will say that the ec should be 15

i would go for an ec of 1.2 and ph 5.8.

An ec of 0.7 for well rooted clones is to low,

What you gotta remember is clones are actually mature little plants. ( a mistake I made as well )

Hows the growth?..is it pale and looking hungry? my guess thats your problem!

If they burn at the tips and claw down its too much..then you need to lower your ec.

As above Id give them 1.2 and see how they go..

goodluck.

No its not...

Its plant dependant, my plants have 0.5 and are in full flower, they certainly dont need anymore so why would a clone which you dont even know need higher EC level's is beyond me...

For cuttings i find formulex is the kiddie to get them going, full nutes may well be too much and you are suffering lockout, although without any pics and knowing the clone its very hard for people to make a judgement...

Like I said Im guessing thats your problem mate..From what ive read and come across 1.2 is a good starting point for clones.

0.5 in full flower...now thats funny

Again ive never seen an ec this low in full flower..

Stick a pic up

In my experienc aerocloners need really low ec.

Aero systems use about half ec of flood and drain for example.0.7 in aero is like 1.4 in non-aero system. Too high for young clones under flouros imo.

I think you have nute burn. That big one has the claw i think.I would flush and come back at ec 0.4 max.If new growth comes back ok you are sorted.

Just my opinion (educated one though). Hope it works out.Your mileage may vary.

Cheers .Papa

thats got to be the worst looking cuttings i've ever seen.

Hands up! I got it wrong on this occasion..appoligess takeiteasy! Feel free to feed me humble pie.

I over looked the aero cloner & jumped in with both feet when in reality Ive never had any experience with one of these

Oen Ive had a look thro your diary aswell..goodstuff indeed your plants are are a picture of health for such a low ec,

Wish mine where that low,but they are at 1.9 - background so 1.6 and only 10 days in flower..they seem happy enough tho.

Anyway this aint about us .....

Hope you get it sorted fella..

Cheers guys appreciate this help. I checked the solution and it was 0.8ec so i have replaced standard ph 5.8 water with zero ec.

How long should i run this for ??

I also have some formulex now, should i add this when flushed and at what level ? or should i stick with ionic grow ??

Cheers

Cheers spankey, fills me with confidence.....

Overnight should do.
Ph will be all over the place most likely.It should steady when you put nutes back in.
Affected foliage will not recover. You should see new growth in a few days. Full recovery in a week. Growth will be strong as roots already well developed.

I just use veg nutes. I start mine at about 0.3 and don't go higher till I'm sure they are looking for it.

I too have read before now that aero-type systems require lower EC levels, bubblers slightly more, and F&D systems slightly more still.

I've experienced this myself in bubblers where I found that lower EC levels than I was used to using, and erring on the side of lower pH as well (going down to 5.4-5.5) worked really well for the plants.

I would stop using the Ionic Grow and see how they get on with just Formulex for a while - you'll find it really hard to over-nute with Formulex, and it contains all the micro and trace elements, so you'll know that they're not crying out for any of those.


e²a: You could also let the pH swing from 5.5-6.0 just to make sure that all elements and minerals have their chance of being absorbed at peak efficiency. Make sure that your pH meter is properly calibrated (and your EC meter, as well).

Seen worse-not by much though.
I'd take bigger ones next time.

Cheers guys

The cutting were bigger but i cut off the larger crispy fan leaves which i perhaps should of left the plant to sort. Will leave them for 24 hours then add formulex at 0.4ec and ph to 5.5 and let it drift to 6.

Wish me luck

You did the right thing in removing any leaves that became crispy and dead - they're doing no good for the plant in that condition, and are breeding grounds for mould and fungi etc..

well flushed them for 2 days and now added formulex at 0.4ec. wait and see now.......

Any news?
For some weird reason I have been worrying about your plants.
I need to get a life methinks.

I use DWC and Aeroponics. for the clones, once the roots are well established I keep them at an ec of 1.2 and bring it up to 1.8 - 2.0 during the flowering stage.

When the colnes have just been cut I try to keep the nutrient mix at a quarter of the suggested level. Also, if you are using an aeroponic propagator mix some rooting hormone into the solution aswell, this will help bring along the roots.

I saw your plat pictures and i've seen something similar when I first used my aeroponics. I think the problem might not necessarily be the EC levels, the nutrient burn could be caused by feeding your plant too often. I work on a 1:4 ratio of on to off, so for every minute on the aeroponics spends four minutes off. I move this up to 1:3 about 2 or 3 weeks into flowering I find this is the most useful. tried 1:2 but the plants didn't seem to like it much.

hope this helps.

My aeroprop was only made for me to get roots and it did this no prob and they are good. The leaf growth is now a lot better but by no way do they look 100%.

The ends are no longer dry/burnt but new growth develops brown spots.

Temps/lights all fine but humdity is in 40's which i think is slighltly low for veg so have been spraying now and again..

I am uncertain as to whether this is because i have left them in the prop to long and they are not designed for this ? ie 15 mins feed/45 off.

Perhaps if i had my bubbler ready and had transplanted earlier they would of been better off ???

Will post a pic tomorrow guys.

Honestly don't know whether to ditch them nd start again tbh.

Cheers

If you took of the humidity dome and the plants were under a HID light it should be ok. If there is nutrients in the propogator it will at as a resovior and grwo the plants. The only problem is if the roots get too big and get in the way. Moving to the DWC earlier wouldn't make too much difference, its just a different way of moving around the water and nutrients.

I'll wait to see the pics before I comment more.... to be honest what you are discribing sounds very familiar to me and I think starting over might be a better idea.... if it doesn't take too much time.

The plants are still in my veg cupboard with 2 pc fans for intake/outtake, small clip fan blowing on them, temps 19-27c, humidity 40-47. I flushed them as earlier described and used Formulex at less than 1/4 strength ec 0.4. It holds 8l, it recommends 10ml/l so added 15ml instead of 20ml.
They are under x2 55w fluro's which are just above the canopy and give no heat. I also give them a spray with water/touch formulex.

All these probs have stemmed from initial overfeed/burn when i first had roots (newbie error) plus having no ph pen thus it went 7.2.

They are growing but some leaves show brown spots some don't and some are weird shape (i think). The roots are huge and now in the nutrient solution and i planeed on having them in main room ages ago but other matters have prevented this.

The pics show the worst older effected leaves and most of new growth has hardly any brown.

Could they now be hungry ?????

Vast improvement. I think the brown spots are the last scars of nute burn and if new growth is green and healthy you are good to go I'd say.

Long roots in aerocloner are not a problem as long as you don't let em tangle into a nest. I seperate em everyday when they get long.

In my opinion they will be fine in aeroprop for a while as long as you can keep water temps down. If they go much above 20 degrees you will get root rot soon enough in my experience.

Freezing some bottles of water and putting em in tank should help loads in this dept. I take temps right down to 15 and let em warm back up to 20ish and do not have root issues. Taking em down that low probably inhibits growth slightly ( General Hydroponics actually recommend 16 to 20 for their aero systems) but this is preferable to root rot in my opinion.Some might disagree but I have had good results doing this.

I think they will make good plants and would not start again if I thought I could move em in a week or so.
In my experience plants that have had abuse and recover can often give great results.A bit like unplanned pruning I suppose.

Might be worth bearing in mind that you now have a relatively large root structure feeding a small amount of foliage so you might need to reduce ec even further. Low humidity also contributes to overfeed issues.(Plants take up more nutrient to replace the extra the are losing to dry air).I have had clones that size happy at 0.2 ec.

Best of luck

Cheers papa, is it worth me vegging them for a bit in in the veg room/buckets, i have 600w hps for flower or could use a 250w cfl.

They will defo be in there within a week, got to get my arse into gear, less smoke more work...

Need a ph pen asap but don't know which to get...

Thanks for help/advice.

I would veg em for a while under the hps. How big you get em before flower depends on how many per metre as you probably know.

I veg until plants fill about one third of growspace.This will vary with strain and planting density and only experience will really teach when they have vegged enough in my opinion.

I think small clones like hps asap as long as its kept about three feet away at first and lowered gradually over a week or so.More lumens more growth as long as it don't burn em I'd say.Opinions vary on this however.

As for ph pen I think the cheap ones should be avoided. Some people get good service from them ,I know, but I went through loads of em when I was starting out.(Maybe I was unlucky)Learning hydro is difficult enough without bringing crap equipment into the equation.
I have used a bluelab combo for nearly two years and can highly recommend it. A bit pricy but three in one -and industry standard accuracy and reliability. Buy the best you can afford I would say. The cheap tool is always the most expensive in the end blah blah blah. I wouldn't dream of starting hydro without one.

Get em in the bubler under hps and keep posting pics.1 watt of air per gallon worked well for me in my vegging tub.This is what Lucas recomends.
I feel an affinity with your girls now. I really need a life.

Papa.
