I'm not sure when this started but I know it has gotten worse since I watered last about 3 days ago. I made the mistake of trying to grow multiple strains in the same room with the same formula. It seems that only one of the strains is effected. The effected strain is querkle (purple erkle x space queen). Unfortunatly, I trimmed away all the worst leaves before I took these pictures. Hopefully you can still get a good idea of what's going on. The room is way overcrowed as it is and even though it would be a shame this late in the game, if I don't fix this soon, I may have to consider tossing them. Lets hope it doesn't come to that.

This is my first time growing soil so maybe I overnuted. Also, the last watering had a lower pH of 6.0. I had previously been giving them 6.6. Everything else looks super healthy with fat nugs already after 3 1/2 weeks flowering. Now I'm really freaking out because today I found beginning stages of white powdery mold on some of the bottom leaves. I've been hitting them with tons of serenade and pruning so hopfully it goes away the easy way. The humidity is about 40-50%

I'm using foxfarm for the majority with about 20% of both perlite and coco mixed in. I have 5 gallon pots under 1000W hps and mh reflectors. C02 is about 1300 I think but I don't have a meter. They've been getting about 1300 ppm of nutes (1600 tds w/ karma and sweet). Room is usually 75-80 degrees. What should I do? Can I bring them back? Should I leech them? Or should I toss them before the mold spreads? Any advice is very much appreciated. Thanks
