I do appreciate all the advice from you folks, it really helps and it also gives me the confidence to know I'm doing the right thing (mostly).
The girls had their first feeding on the 4th, 20 days from sprouting. I followed the directions exactly for a light feeding. Using Fox Farm Grow Big 6-4-4. I mixed 2 tsp in 2 gal of water. I think that my soil (Fox Farm Ocean Organic)already already has enough nutrients because I'm now getting the claw look on the fan leaves signifying too much nitrogen. I think I should have waited anothe week before feeding. To be on the safe side I heavily watered them twice now to flush out the excess nitrogen. Is this the right thing to do?
