Chuddanswered grow question 2 years ago Hi bro, to start, its kinda strange that your runoff be lower than the water you put in. this suggests that your medium is totally out of whack. what usually happens is the runoff be slightly higher ph due to build up of mineral salts from our feeding them. secondly, if this plant has been harvested already then I'm guessing that you found out what the problem was.. my money is on nitrogen toxicity and overwatering.. hope this helps man, happy growing!
