Gave the girls a flush and a complete water change this week. That was only the second water change they have had this grow. I have just been letting them drink the reservoir almost empty and then filling it up with fresh nutes. The 5 plants are drinking about 4 gallons a day combined. Been running AC when the lights are on and the dehumidifier 24 hours a day. All of the plants are showing some decent trichome production. Running 1/2 tsp maxibloom and 1/8 tsp beastie bloomz per gallon every time I add water. Seems to be keeping everyone happy.
