The heat wave lessened and temperatures got a bit better. Switched to full spectrum lights (375 true watts). Fed about 0.75 cups PH'd water every other day.
I haven't started a coco grow from seed yet, but most things that I've read say there's better growth starting with nutrients as soon as the seed leaves have opened.
@Green_Coffee, You could be right, she seems slow growing so far, which could be due to the heat wave we had here, but I did start my nute routine a bit earlier with this girl than I would normally do. The great thing about her not being an auto is I can extend the veg period as needed.
