nutrient problem maybe

[badbillybob]

if you are just starting, soil, or coco is far easier to be honest.

just dont over feed or over water them. thats the 2 biggest mistakes i see beginners make in mud.

higher temps arent as critical in mud/coco, they can withstand a day or two of that, although high temps throughout will cause airy buds

good luck, dont give up.

I’m afraid I have  to agree with the other guys the roots don’t look great, as for the marks on the leafs that’s the least of your troubles if you carry on the way you are you will Be disappointed by the final results.

[zen-ken]

Something your putting in there is not agreeing with the roots and you didn't root them out correctly in the first place I'm afraid.

(cover the stones up)

 

 

Im unfamiliar with Remo nutrients and would need a lot more information to help you....(you using the velokelp? )

 

Start by washing the shit off the roots, trim the ugly leafs off, bleach the system.....after that a regime of top feeding and love and you can get them back....Ask @Dsmile

 

Without temperature control on the pots your always gonna be up against it in this type of system 

 

However

 

@badbillybob is very correct Im afraid......with auto's you don't have the luxury of veg time to be pulling them back so if your gonna continue act fast

I think this is the most common reason for failure in dwc bud...

Couldn't agree more brother....these new blocks Im using and correx covers I made have been a god send for lateral rooting.

 

You cant hang a sodding great root system on a few strands

Don’t know what equipment your using but looking at your roots i would say it’s down to the temperature of the water try using a low powered veg light to reduce temps or ideally a led, once there’s a bit of canopy the light won’t be hitting the oxypots directly then going can crank things up

An overpowered air pump in the wrong place will also raise water temperatures.....he would be better off insulating the pots, covering the stones and using the old ice technique rather than reducing the light  (assuming you're running the correct PAR)

Can’t argue with that mate

you could try cleaning everything, hose off the roots and dose it with endrosan 8.

insulate the tubs with silver bubble foil insulation.

might work, but i wouldnt put money on it.

 

me? id rather waste money on 2 weeks electric than 10

 

good luck

 I think its a mixture of a touch of root rot  from heat and a slite  deficiency and I recon I was keeping ph a bit too low at 5.5 so it want sucking some nutes up   I'm going to keep it at 5.7 from now on

when I looked to day roots seemed a bit better new growth and more growth on top,

 

 

 it was due to its 4-week feed and water change

 

so what I did was I put air stones

 

In the spare buckets with fresh water and hydrogen peroxide for an hour and poured some of it from the top through net pots

 

then i removed bad roots and gave am a shower with fresh water from the showerhead

then I put em back in clean fresh dcw buckets with the right amount of peroxide and nutes

 

Then realised I got some silver bullet root protection stuff I got free with oxypots id forgot about so put some of that in removed bad leaves and done some Low-stress training

 

 

that was this morning and now they seem to be doing really well and picked right back up got some ice bottles as well to cool water

[smallbuds]

There 4 weeks old today so and not bad size and the was more healthy growth today so I recon there worth  giving a chance for the next grow I'm going to can the oxy pot for one bug res with two net pots to keep every thing more stable and start with something like hydro guard or silver bullet from day one and temps will be getting better now were out of that heatwave

the air pump is outside the grow drobe and all air pipe is black so its not that as for lights  there are two vipspar 300w reflector leds in there one per plant i think ther draw about 130 true watts each i also have a temperature controlled fan controller for inlet and outlet fan at the moment I was trying to keep noIse down and i aM using a 4inch extraction fan

 

but i have a big ass 6inch as well and as im venting into loft ill change fan too the big one for next grow aND MOVE FAN into LOFT ABOVE TO KEEP NOISE DOWN

Yes I'm using the  velokelp I got the full starter kit so was using the optional stuff as well  following this chart i found for autos the chart is the amount per liter of water

 

so basically were at week 4 today on chart I wondered if id been keeping ph too low for some nutes at 5.5  so ph`ed new water to 5.7 and will keep at that

 

i do haver a eseshals ph pen meter and ec one too  but not shaw what im doing with EC so was just doing a compleat water and nute change once a week

The problem with the lower PH is it'd difficult for the girls to uptake the calcium at this range (your necrosis...the spots) so I tend to keep to the 6 mark until early flower when my concern turns to PK levels and then I will run 5.6-5.8.

 

Do not get disheartened! you got this .....they look good and there praying....understand your technique and read the plants....there alive and trying to live in the environment you created...respond to them....look at others diaries and you will see that me and other members have taken plants looking worse than this to over a g/p/w

 

It may not even be rot tbh (pythium stinks...you know when you have it)....its just a huge root system trying to feed a plant through too few points causing lockout and bacteria build up (hence the dark spots)

 

Im not gonna sugar coat it....the schedule you have is for running plants under optimum conditions ......your lights are shite.......the rest of your equipment sounds like its good to pull tree's 

 

Your gonna need to lower the feed based on the fact the lights are giving half of the optimum light at best (a quick look tells me the blurples are pulling less then 500 PAR.....most peeps here run a 1000)

try to top feed for a bit to promote lateral rooting 

 

The news of improvement is music to my ears....long may it continue 

 

Very very basically in DWC (I can go into more detail....not sure on your level so please.....im not meaning to be condescending....mineral nutrients....dont put organics in at all till you get the hang of it )

 

Assuming

Water level dropping :

If EC drops - then your not feeding enough - up the EC

If EC raises....lower EC....plants are leaching back....consider a lower EC and build back up

If EC stable.....harmony 

 

Leaf tips burn....back off EC....plants look light in colour....up the EC....leafs green and 'praying' .....leave them alone and give thanks and praises

hi mate im throwing in the towel with DCW  I think due to the location I'm never going to keep the water temps in the range  I tried peroxide to treat and sterilising everything meant they were looking ok at first but slime is coming back now and plants are looking really sick

 

so I decided to rep em up sterilised again and do a go soil with an auto pot system   I only wanted a 15l  two pot system but got a deal on  4 pot as the shop let me have the 4 pot for the same price as a two so got two spare pot and valves for nothing

 

 

[Heisenberg91]

I have currently gone back to soil
