So only the top leaves are yellowing slightly? temps at the top of plant are at 21-22 at the highest. Cant understand it really. Nute strength has been lowered to 1.02 roughly making it about 1/3 strength. Any suggestions, will this affect overall yeild?

GT.

just looks like a tiny bit of nute burn to me ..?

Thanks Tree man. I dunno if its worth me flushing through some ph'd water or not for a few days? Hopefully it doesnt progress. Its weird cause some say that the yellowing is normal when in flowering but i'm a bit unsure?

I noticed that Owd says they need less food in flowering, funny that i would've thought that they would've needed more as they're having to produce bud. Shows what i know

Heres a whole shot of her. I hope she thickens out by then

GT.

What week of flowering are you in, what strain issit?

Barneys utopia haze is the strain and its at day 58 out of what they say should be 70-80 days. I could kick myself for going for a strain that i cant seam to find any grow reference to but hey...we live and learn.

So what do we think?

P.s, thanks for taking the time to reply i really appreciate it.

Looks like nute burn to me how far and what power is your light

....sure it's not the closeness of the light?...plant looks healthy overall.

The plants are 8" away from the coolttube. I did think it might be this and i was thinkin of givin a little lst just to pull it away from the light a bit. Plus can bud Lose THC?

Sorry, yeah its a 250w hps cooltube.

....put your hand in between the bulb and the plant and you'll know if there is a heat problem. Be careful mind.

..when you say losing Thc are you saying that in relation to the rest of the flowers on the plant, the tops appear to have 'Lost' thc? ...if so then it is even more likely the closeness of the bulb inhibiting resin development, perhaps too close a fan as well.

Thanks mate, yeah i did put my hand under the light and didnt really feel much heat coming off after even a min. I dont currently have a fan going on them as the temps were'nt that high so wasn't sure if i needed it?
I was gonna have it just blowing over the top but worried about wind burn and its not an ocillating.

When i say losing THC i mean it looks like the THC has gone from some of the top bud compared to how it was a week ago. It looks like the side buds have more THC then the top/main.???

Clueless as to what to do now.

What are your lights off temps? 21-22 is kinda chilly for lights on - thats more like a lights off temp. Low temps can inhibit growth and potentially cause lock out issues in the rootzone.

i'd flush two days, and re-continue ferting.just a litle less than you previously did.

at your temps the plant will not" loose thc".
The plant is fattening its top buds.

add a lill extra nitrogen coming week, and start flushing at 65 days.
harvest at 75 ( my guess).

Thanks for your input mate yeah i did think the temps where a little low. Light out is between 17.6 and 18.2 degrees. I was thinking about adding another 250w that i've got sittin around but thought knowing my luck it'd reach over 26-27.



Thanks Psycho-tik. I was thinking about flushing for a couple of days but thought id wait and see if anyone suggests it, and that'd be you so i'll get onto that.
Thanks for the heads up for harvest as well. With no experience i wouldn't have a clue. I've been reeding Owd's guide to flushing but without knowing how long the pistils will take to change i dont know whens best to startflushing.
Pistils on the lower buds are going orange before the tops?

What percentage of orange pistils will indicate when to flush? 40-50%?

Thanks again though to everyone whos taken the time to add ur input.

Peace and love
GT.

pistils are a poor indication.
get a decent magnifier that allow you to see the trichome heads.
a fair amount of milky trichome heads indicates ripeness.
With hybrids like yours I wait untill I see few amber trichome heads= sign of well stoned herb.( actually amber colored heads are considered over-ripe, but also contribute to a very lethargic buzz= my favourite)

best of luck.( btw , 250 watts usually makes a rather late harvest = add an extra week to what the breeder says)

...that sounds like good advice man. .....incidentally what is your current E.C? - noticed you are using the wilma system also, flood and drain ....what are your tank temps as you may need a tank heater if its too cold.

Cheesy

Thanks for the sound advice m8, ur a diamond.



no res temp unfortunately gonna go buy one 2mrw (floater) The E.c is at 1.05 at the moment but was at 1.24 on the 16th when i first added 1/3 strength PK 13/14. Stopped with the PK now and the canna nutes are down to 1/3 strength (13.3ml to every 10ltrs)

Dont know where i'd be without all ur input though.

Peace and love.

Well this is the top/main at the moment as it seems to be the only affected area.

I still dont know if i should give it any LST at this late stage? if that matters?

I've changed the water to just ph'd(5.9) tap water that's sat for a couple hours. I'll give her this for a couple of days as recommended, then low strength nutes before flush and soon chop.

Anymore input would still be appreciated though.

She looks a bit rough at the moment and i'm worried about the yeild suffering.

Heres a couple of pics from left to right.

Easy, GT .....just looking over all your specs and your diary... Couple of Quezzies..

Notice that you have said that you have a wilma system and your using the flood and drain technique? ...how is this possible, i was under the impression that it was a re-circulating system run with drippers and therefore running continuously. Or am i misinformed.

Second, looking at your diary pics your E.C appears to have been fine around 1.3. Here the plant looked great. Why drop it more!

If you are running flood and drain is your pump on then off for a while? ....i have the feeling your plants are very hungry under bad conditions. And you could probably do with a 400 bulb in that space to be fair.
Do you have any extraction? Air circulation is very important.

...also that looks very sativa looking so i would expect a long flowering period.

...and leave your water to stand overnight to release some of the chlorines and raise the temp....cold water'll shock your roots into doing nothing!

Cheesy

Hiya mate,

I made a mistake with the flood and drain part I've actually got it set up in a bit of an difficult way at the moment.
I did have a 400watt but the temps where getting to high to manage without buying all new extraction equipment again which i just couldnt afford at the moment.
I just bought a 250w cooltube to keep the temps down to about 22degrees as my tent is in a very well insulated loft :S I've got a 125mm carbon filter and a 100mm bathtoom fan as an intake.
Clip on fans are in there but not running at the moment cause i was worried about wind burn as they're not ocillating fans.

As for the wilma because its in the loft i cant remove it very easily and clean it so..........I bought 3x10ltr builders buckets that i've been using as a res for the nutrients with the pumps in. Water is changed every couple of days and is left to stand before adding nutes and then again before feeding. Water is around room temp.
The Wilma res is just purely being used for the run off water at the moment
I only lowered the nutes because they started to look like they do but now i'm flushing for a couple of days i'll try 1.2EC after???
I also noticed last night that the root had grown so much through one of the holes on the pot, it was actually in the run off water which has been there for a while only by a couple of mm but enough to upset her it seems.

The feed cycle i have for her at the moment is 1min, five mins after lights on. Then again six hours later for 2mins and then again about 25mins before lights out for 1min.

This is my first time at growing absolutely anything though so i'm still learning, especially with the aid of everyone on here.

So what do yall think?

Peace, GT.

So basically you only feed flowering plants for 4 minutes every 24 hours?

I will be using the wilma with clay peebles with the flood drippers and was told to feed for 15 minutes at least every 24 hours when in flower

Thats pretty much what i've been doing she seems happy enough although now i'm starting to doubt myself. Is this not enough then i take it?

Need some advice plz...

High guys,

You should be flooding your system every 3 or 4 hrs,some say not to bother flooding at lights out but i never bother to change my timer and continue to flood throughout the dark period and ive never suffered bud rot or had signs of overwatering.

Peace

HH

Thanks for tha advice mate.
I'm nearly done with this one and think with my next grow i'm gonna grow 5 or 6 of the same strain and really try to access their needs, i.e the best ph and ec for the perticular strain and also what sort of water cycles are best and how long how often etc, etc...try and turn it into some sort of science experiment...it'll feel like i'm back at school

Peace out.
