I might possiblly have a fungus growth going on, not sure, I fed the healthier ones with mychorizae and slf today and hoping that helps otherwise i guess they'll just keep going until they're done. some of them seem totally fine which is what's been frustrating the hell out of me, until 2 days ago when i checked the ph on all of them and now all of a sudden all of the plants have dark brown/black spots. I'm not imagining things, may have made things worse, but certainly the issue was there before i started chasing my own tail.
