I water once a week are when soil is dry I have nutes mixed it the water as stated on the bottle. I am using Botanicare Pure Blend Flower Formula 1.5-4-5 PRO bloom soil formula. I dont have them under as much light as I think she need but its a GE Daylight 60 Compact Florescent and GE reg 60 Compact Florescent for a bit of heat. My temp stays around 77-80 never higher.
