Hashyanswered grow question 5y ago When you water you should water until you get run off coming out the bottom, then wait till top inch of soil has dried before watering again. Your temps are also a bit low. Ideal to get around 26c during lights on. It's hard to judge at times if it's over or under watering. Check your soil now and see how dry it is. If dry water until you get run off. Good luck.
