Here is a basic run down of my grow right now:
I am growing in a coco/perlite mix in 3gal containers under 600watt HPS lights.
I am using AN nutes at the following levels Micro(5-0-1)@4mL/gal, Grow(2-1-6)@4mL/gal, and Bloom(0-5-4)@4mL/gal and a Cal/Mg Supplement(2-0-0)@1mL/gal. My water is pHed around 5.8-6.0, right before I add nutes and I always check after adding nutes to be safe and it remains constant. I usually water when the pots feels light.
I recently bought a dehumidifier, thinking that if it were mold/fungus, it would slow the pread. With the dehumidifier, my humidity hovers right around 40%-50%, with temps usually ranging from 75-85 degrees.
Also, I originally started in 1gal pots with a straight coco/perlite mix. A week before flowering, I transplanted into 3gal pots and since the store was out of straight coco, i picked up a coco mix that had ammendments(perlite, lava rock, earthworm castings, composted chicken manure, fish bone meal, bat guano, seabird guano, kelp meal, silica, alfalfa meal, humic acid). This kind of why I think I am seeing the nitrogen toxicity, because I am giving the plants nitrogen through nutes, plus all of the nitrogen I believe it would be picking up in the ammendments. I could be wrong.
Let me know if you need any more information then what I provided.
Thanks!
