First Time Growing Anything

My state voted YES on recreational on 3 Nov, I started seeds germinating that same evening! I started 4 and had success with all of them. Had sprouts coming up by the 7th. I planted in 64 oz paper cups using Fox Farms Coco Loco, with a couple of inches of coco coir on top of that. I wanted to use the coco coir layer as a bit of a buffer before the roots hit the Coco Loco as I had concerns that this soil might be a little on the "hot" side. I used paper cups in the hope of achieving a stress free transplant down the road by cutting out the bottoms, cutting down the side, placing it in the receiving soil and hen simply pull the shell of the cup out of the dirt.
