I am currently growing an OG kush clone under 400 hps in a dr 120 tent. Using foxfarm soil, and big bloom, ph levels have been maintained, and temps in 60-75 and usually in 50's in dark. I was wondering what is wrong with the curling leaves??? Do I need to prune them, is this normal???

you have been over watering or the humidity is too high in the day or when they sleep. a dehumidifier will be fine for you.

your newest leaves are not showing any signs of over watering which is good. but your older leaves are showing those symptoms.

only "flush" once every 2 weeks or so.

Isit just the pic or are those bottom leaves very dark green?

EDIT: 50F in the dark? that seems very cold to me aswell. That prob isnt helping with the stress on your plants, they must be almost outside if it gets that cold?

Your PH is way too low for one, shoot for around 6.5

Your temps are too low, aim for the mid 70's.

The new growth appears to be curling from over watering. Let the soil dry before your next watering. I would not leech at this time, as your color is good and plants are not burnt. This is definitely an over watering issue. Leeching will only compound the problem.

potmonster gets the prize with his astute observation of the dark green over nitrogen attack. I had a few Grape Apes that someone said were OG and they did the exact same thing when they had too strong of nutes. I had a buddy who also had one and he WAY OVER NUTE'd and too much HEAT made his curl like that, he was about 85 f in his room. Could be what you got there. Flush that baby and cut the nutes by a half and watch her respond.

Soil isnt really my thing but I would say it is a humidity and PH problem. I know soil requires a higher ph than 5.5 to 5.7 that is hydro tolerances try 6 to 6.5. I hope this helps

NOt really permanent unless you have burnt or damaged leafs...

They will take a long time to come back and may still retain a little of the curl...

Keep an eye on new growth as that is the best indication of the overall plant IMO...

The rest of the plant looks in good shape though and it just might be a strain deformation...

Sometimes my inner leafs grow a little funny like that...
