RT ......... did you see the pic I posted of the leaves on here? I dont have a test kit but I have done as much research as I could in the short amount of time ive had since this prob happened and calcium or Mg is what I had pretty much decided on also. I havent had a test kit to check the ph#'s and that kinda stuff, no $ so how would I go about straightening this out or even guess-timating on what mix to use to fix the calcium issue?
