Thats very interesting. Someone else told me the koolbloom was the problem but didnt explain, and of coarse i didnt listen. It makes sense though. I started a flush last night. My flushing habbits have been poor to say the least from the get go, like i didnt flush them ever untill about a couple weeks ago. Could that also be part of the problem? Im kind of assuming that. Next time, i flush every 2 weeks. What do you think about that white residue? that always shows up before i get little black dots then the leaf dies. It looks more clear and slimey in real life. Man im glad this forum is here, all us rookies would be even more confused without it. WH, thank you for taking the time to answer.
