One of my plants top leaves are really starting to discolor. They are turning brown like they are over ferted but she get the same meal that the the other two get. I've tried just straight water but no help. She is in a three gallon bucket and approx. four feet tall. My question is what are the symptoms of root bound and if the problem persist what would be the downfall of harvesting early with only 30-40% of the pistil being amber?
