Leaf Cupping Help!

Hi Rollitupers,



Newbie here wondering why my babies (Blue Dream) leaves are cupping. I have spent a few hours reading this past week about leaf cupping and tried various things I saw on the web (Checking PH regularly, raising lights, added more fans) but the problem is still happening. The leaves were yellowing but I added Cal Mag and the new growth seems to be a nice green color. But the cupping seems to still happen. I don't have a ppm meter so I have been going very slow on the nutrients. The leaves also suffered water burn because I was spraying them with water like a dumbass!
PH stays between 5.7-5.8 and temps don't go beyond 75-76 (past week temps were at 70-71). My nutrients are Flora Nova Grow/Bloom and Cal Mag.

My setup
I have one plant in a 5 gallon black paint bucket with two 1inch air stones, and another 5 gallon bucket with 2 plants and two 1inch airstones. 400 watt MH/HPS. They are on a 24/7 light cycle until I buy a tent and bloom them. I am getting four 5inch air stones that should get here soon for more bubble, I also will add another pump.

Well when they roll up like that it is usually heat or humidity related...what is the temp of your bucket/s?

Possibly pH issues...check for it being too high...when leaves claw down the other way they are usually overfed, but up like that usually just means it is too dry or too hot and the plants are having a hard time holding onto their moisture, so the plant rolls the leaf up to catch any rain that might fall...also why leaves droop down right after you water them..they have had enough and are trying to stop catching more...

Hell I looked at your pics again and I wouldn't even worry about the cupping the plants are still pretty young and sometimes younger plants have no direction and do weird things growth wise...

Thanks for the fast replies! I will keep you guys posted.
Also, I'm pretty sure I fucked putting 2 plants in one bucket. Is there anything I can do about that? Maybe sacrifice one and trim the fuck out of it? lol
You mean check the temp of the water?

You said you use flora grow and bloom, do you use micro also? you know that that's a 3 part series.
that's what I use and it works great.

go ahead and take those yellow leaves off so you can concentrate on the new growth. they will not recover and will distract.

I believe mine is only a 2 piece set. http://www.amazon.com/General-Hydroponics-FloraNova-Bloom-Quart/dp/B0031FFFEW/ref=sr_1_2?ie=UTF8&qid=1340517848&sr=8-2&keywords=flora+nova
Just Grow and Bloom

Also, I have 2 plants in one bucket, do I sacrifice one or just keep going and maybe trim one plant a lot so that it doesn't block or touch the other.

Think it might be getting worse?
The single plant is starting to look pretty good in my opinion.

What room temp . it from heat or light too close .. raise the light far up you can , control the heat keep room temp 74 - 76 . Make sure Ph stay at 5.8 .... give it a few days it will get better. the leaves wont get back to normal . wait for new growth . Room humidty kinda too high . keep it 40 -45 good luck .
