I’m in flower with my Sour Lemon Hash Poison and things were going great until this last weekend. I developed a bunch of fungus gnats on Sunday, and today my leaves are looking like this. How can I safely treat this in flower?
Hi there, it could be a calm/mag deficiency, if when you rub the spot it transfers to you hand then its mold/fungi, if not then its more than likely a deficiency or ph issue.
