Awesome responses guys, thanks alot.

So it appears that the plants are recovering a bit, the mazaar's leaves are becoming less dark, more firm, and the GDP is not showing increasing of folding leaves but a positive return to normalcy, though it still has plenty of folded leaves, just not so much now. Aswell the flowering seems to really be kicking in.

As i have been taking out N, this would seem to support the N overdose hypothesis. I mainly took out N by cutting back on micro from the lucas formula (0-8-16). I did add more bloom to make up for the lack of micro, to keep the ppm the same. Is this an error? If so how would i tell?

ALSO,

I havent been using cal mag. I'm running R/O water and now am in the second week of flowering. Perhaps some of the folding lacklusterness could be attributed to this? I dont know what the effects of not having enough CalMag look like. If i need to add CalMag, how much? I've heard that it lowers pH. Would i need to counteract this with PH UP? Or is there some other means of doing so that i'm not aware of (if i would need to adjust the ph that is).

Also with the powdery mildew. I've got the humidity down to 55 during the day, with a temp at around 68-75 during the day. It seems to not be going wild or getting too much worse, but i got some neem oil spray to treat it. I need to know how should i apply the neem and when, i.e while lights or off or on? And also, would it be wise to invest in a dehumidifier for preventative means against the midlew, given my current air conditions and using the neem as a treatment.


And finally- I'm using a 1000 watt hps currently on 12 plants in an 8x8 space. It seems like the plants could use more light penetration for the lower and outter facing sides of the plants not in direct light. Would it be wise for me to add another light. If so, can i just get something like a 400 watt and put it next to the 1000 watt, or do i need two 1000's?

Thanks for any good advice, greatly indebted to it!
