Northern Lights Autoflower First Grow :)

Germinated 2 more seeds - one 3 days later and one 6 days later. First girl is doing great and really growing now/ loving the outdoors. My second seedling got caught in the seed casing and I thought it would shake it off on its own but that has seem to stunt its growth. It is still alive and slowly growing but very yellow. Might be over or underwatering it I cant tell. Plant 6 days behind is doing as well as the first one just behind almost a week. Was using a spray bottle to water and think I may have underwatered a bit. Moved onto a large watering can and gave the first feed of 2 tablespoons of Fox Farms grow big in a gallon of water. Glad I ph tested cause my water from the hose was like an 8 where the inside brita water was 6.5. Fixed the ph and watered.. pretty soon after my bigger plant perked up. Plants are fully outdoors now that nights are warmer - before I was bringing them in at night. Think they get 11-12 hours of direct sunlight a day.
