here are a few pics... the yellowing isn't as bad as it looks here...that is due to light... It is yellowing a small amount none the less. the leaves up top are looking very dry as you can see here...no burnt spots etc... I tried to check my oh using both my needle meter ( unreliable) and the pills version ( also unreliable) and got between 6.5-7.0 I watered yesterday and didn't include nutes for the first time in awhile but they looked great this morning. I also started them on 18/6 from 24/0 last night, but as I said they looked great this am... what could be the cause? lights too close? fan on too high? too hot? lack of nutes? Please help.... Thanks guys
