Sour Diesel Autoflower

I sprouted the seed on a paper towel. The tap root had a j-curve. I am using a five gallon pot ( not filled all the way, so maybe 4.5 gallons). I’m growing in my sunroom to get the most light. This room has large eastern windows and one southern window--which is blinded for privacy, but I opened the blinds enough to get some light in. I am also supplementing light with a small LED tomato light. And I have a 45W Black magic LED array, which I can introduce if need be.
