Hi - I posted a thread the other day entitled 'Help diagnose problem - pictures for reference'. Mag and Nitrogen deficiency came to mind. I ultimately changed and did a new batch of nutrients and some of the yellow went out of the plants. I think general concensus was also that temp was too high in the box. It gets around 92 with lights on. (90 today with 60% humidity) Fellow grower in this area keeps entire grow area around 95 degrees all year and he advised temp wasn't a problem. But, he also grows in soil and they are in an open room. I have circulating air on ours in the grow box but am thinking of moving to cooler room so intake air will hopefully keep temp down some.
ANYWAY - Here are updated pics. The roots actually are looking better than they did. (kind of look dark in the picture but they aren't as dark as they look) The leaves were getting more green back to them (you can look at the pics in the earlier thread mentioned above). But now they have spots on them now as the pictures show. I'm wondering if it's heat or if this is just trauma from the problems the other day. The only thing is some of the new smaller leaves have a curled brown tip.
Have a DWC system and using Technaflora nutrients but open to other suggestions. Thanks for the input.
