I am also having the same problem. I am about a week into flower and all of my new growth is coming in yellow, but it seems to turn green after a day or so. None of the other leafs are really damaged. I use ebb and flow and flood into hydroton. I flood 4 times a day. i flood twice 10min. then 15 then 10 again an hour b4 bedtime, 3 hrs apart each time. i am using a 150watt hps and 3 cfl's. The light is prob about 10in. away. I have a fan in the closet and an exaust fan blowing out. i dont have any air coming in except when i open the door. I sometimes leave the door open, on warmer days. The average temp. is about 75-85, mostly in the 80's. MY humidity, between 40-50%. Everything seemed 2 b going great until recently. i dont have an EC meter or anything like that... so i just make sure i dont over do it and i change my res weekly. My PH is always around 5.8-6.4. not exactly sure because i have a cheap fish tank test kit. I try 2 adjust the PH with nutes... but i dont add very much at all. I use Flora Nova and my plant is a high yielding sativa.. not sure the strain. but its good and its second generation hydro fem. seed. I Just dont understand how the new groth can come in yellow then turn green. its not all of the new growth tho. just some of the branch tips... i need some help too. Any thoughts or ideas? I can post some pics 2morrow.
