How much should I be watering?
Before I thought 1.6g/day now I think .8 to 1.2 g per day is fine. 3x 5 gallon pots in a 4x4 in fourth week flower... co2 high temps etc
Early in flower they drink a ton but 4 or 5 weeks later they really slow down. Good chance you've been right the entire time. As long as you're giving some time for the topsoil to dry, you should be good.
