I don't have a fan running in there at all now, at least not full time. I did have a large box fan going, but I discovered that the fan motor was significantly adding to my heat problem, so I turned it of. Now I only turn it on for about 15 min in the morning and evening to exchange the air in the closet.

Yes, I'm using hydrotron.

No, I didn't have time to grab any photos this morning before work. Sorry, I know how much that helps in the "what's wrong with my plant" game.

if your plants are eating the numbers down...i'd up the ppms.
Yeah, I added nutes to the reservoir last night to bring it back up to 950ppm. Either my math was off (doubt it) or the plants were really hungry, because it was down the 870 this morning. I'll top them off again tonight and see what happens.

To be honest, I'm not sure that *is* my conclussion. I'm a new grower, so I don't trust my own instincts yet heh. That said, I've ruled out everything else I can think of, so that's all there is left. If anyone's got any better ideas, please speak up .

Also, consider changing out your whole solution.
That thought's crossed my mind as well. Although, again, I'm really late into flowering - just 1 or 2 weeks left - and I know a lot of growers like to flush the nutes and let the plant feed on itself. Also part of the trick with the Lucas formula is that the nutes are never replaced, so that by the end of your grow most of your N has already been consumed and you don't need to flush. Replacing the nutes might be counter productive. I'm hesitant to add a completely fresh batch of nutes in, under the circumstances.

To all as an FYI:My TDS uses a 0.5 conversion, so 950ppm on my meter [email protected].

Thanks for all the input.
