Big Push for Blueberry Kush!!!

All 3 of my seeds had a form of helmut head, A#1 and A#2 had the shell on one of the first leaves(forget their name). I misted them and carefully removed with tweezers on day 4. A#3 sprouted with the shell fully attached. I've tried pulling it gently put too afraid to kill it so I spit on it(heard enzymes in saliva can help) and keep it moist by misting it throughout the day. I watered them once since planting them (I fully saturated the soil before planting the seed). First feeding I gave each about a 1/3 of a gallon or a lil less. I mixed 1/8th of a tsb of Flora and 1/32 of a tsb of macro nutes, along with 2 ounces of Vermis Terra.
