I really don't know what's going on. It seems like a fungal disease but I really am not sure. I've seen no bugs. It started near the bottom and is moving up the plant. I'm removing the worst leaves, but it's getting worse. Any ideas?
I see standard nute burn, flush with 3 times the volume of the pot allow to drain overnight...back up with a regular spray of neem oil, organic and offers good protection for bugs and molds/fungi to my blog: http://forum.grasscity.com/blog/1093/entry-9829-fl... http://forum.grasscity.com/blog/1093/entry-9709-ne...
