Beer almost ruined half a year of work. Long story short, a space heater got the room wayyy too hot during their off cycle...and I run it on the colder side when the lights off. Dealing with some powdery mildew but containing it with a foliar spray mix of baking soda (sodium bicarbonate) a “splash” of h202 and a tiny drip of soap and applying with the lights off. Throughout the grow I am consistently using 3/4th the recommended doses each week for their hydro line. I fill 4 gallons but dose as if there’s only 3 gal. Near the end of the grow I am filling 4 gallons, still dosing as if 3 gallons, however the root ball would cause the bucket to overflow so I have to dump about 30% away to other plants so my water level is where it should be. A little more than halfway full seems to work, and if it is slightly too high, the plant will drink it down where it is fine by tomorrow
