Fox Farm soil grow. Plants are one month old. I Fimmed them on Monday. Light 600W (?) Wills from Amazon costing $64 US. I have heard that the light actually is more like a 200 watt so I supplemented that light with two 100 watt SIT’S. The plants really started to grow after the additional lights. Unclear about how to tell when to water and fertilize. I have a few crinkly leaves and small brown dots on several of the leaves. Thanks for any help.
