Seedsman White Widow in Living Soil

This week I fed them with a flower compost tea, 3L per plant. I noticed browning on some of the pistils, and realize it is much too early for that. I think that my temperature was too high and the plants were overheating. I have turned down the intensity of my light, and have been able to lower the daytime temps to around 78F. I am hoping this will keep my plants happy! Otherwise they are cruising, but drinking lots of water. Starting to smell really good, like berries!
