I hope someone can help. attached are pics of my plants. The lemon skunk I have is about 2 and a half months old and I just put her and others into flower. I've noticed the PH is high (around 7.5) and the new leaves on top are drooping. The last time I watered I used plain filtered water instead of the guano tea I usually use. Could it be nute lockout or over-watered? I have a total of 6 ft, 4 bulb T5's. Any help would be appreciated
