Use a mixture. They both pretty much got the same stuff, but Alaska Fertilize has more N in it which is great for a young plant that is in vegetative stage.
You flower in NE Ohio? Me 2! haha, I can't say what county though on here. Anyhow, for Northeast ohio, Mid august to beginning of september is when flowering starts. I'm a reliable source since I'm from here :P
Hm, are those pots I see? Why are your plants still in pots when they are in the ground? If you have a bottom on it, that could be holding the roots back which is stunting the growth.
Your plants look pretty damn good. Some strains don't grow as big as others do. Plus your stress to the plant probably caused it to not grow as big as it could've been right now. Who knows, that could eventually change, marijuana is a very mysterious plant :P
