cutting the superthrive. Going to check and keep a eye on bag temps that may be a cause it is a cement floor. I did get a sample of some cal/mag stuff in the mail yesterday. I talked the the guy at the local grow shop and he said sounded like nitrogen or mag. But i didnt have any pics to show him. But he said to bring him a couple leaves and pics tomorrow and he would have a better idea. But yeah I would lean toward it being nitrogen. Guy at the store said it was unlikely over nute. It turned from good to all yellow two days after straight water. I probably washed a lot of nutes out. I will keep you all updated thanks again
