Right, that's kind of why I had questions about a glob.....I put a glob of molasses in my hydro system once and fried my plants pretty royally so the glob working for everyone.....

Poor drainage can lead to ph problems where ordinarily the plant could take it....hows the drainage for that plant?

I think the cold night temps can also be adding to your issues but I'd love opinions from others about that. Is the plant on the floor?
