Im about 20 days into veg with a t5 8bulb and 10 plants. 6 different strains. They are lookin beautiful. and strong. Perfect temp at 78 during day. around 65 at night. with 40-50% humidity. ....the problem is a white mold at the base of the pots and a little on the top of the soil. The white guano pieces in the soil are also turning a little yellow. Is this from the water? im using a brita water filter from tap water and was thinkin of buyin bottled water. I also just started nutrients but only a half tsp/ gallon. Can anyone help me! Peace
