I have a nearly two week old plant that i've been only watering and giving no nutes. This is my first grow so I have no clue what is happening with the lower leafs.
That's normal. Those are the cotyledon leaves (first leaves to emerge from seed). Plant looks OK. You'll want to transplant when you see roots creeping out the hole in the bottom. Sounds like you already know more fertilizer won't make it grow faster/etc...but the time is coming when you'll want to start feeding it. Ease into it...1/3 to 1/2 strength....then work up to a full dose. good luck!
