Keep a eye on the leaves, flush with water if you get any yellowing. Do you flush every now and then with plain PH'd water? I dont know loads but i have read alot! I have almost killed mine many times but the Easy Ryders just seem to bounce back once i got it right. check out my easy ryders still 5-6 weeks to go but are 8 week already dont know why but they didnt flower. I did shock them a few times
