First grow,all sprouted from bag seeds, all seed came out of just a few buds,so they really must be from the same type, at least I would think so. Started germination about 1 month ago. Took 3 days to sprout. Planted and then replanted in bigger pots about 10 days ago. Pinched the tops(2 topped 2 fim'd) 2 days ago. 18/6 schedule. 300 watt led light. Temp 80 with lights and 70 without. Why do some have fatter leaves than the others? They look so different.....is this just mother nature? Do they look ok? They are really growing quickly now, I am amazed when I look in on them after a few days of not seeing them. This sure is fun!
