[420bob69]

So i am super new to growing and am about 2 weeks deep. here is my set up...4 40 was florescent lights using the full spectrum bulbs on 24/7 , i am using scotts peat moss dirt, small fan in closet with temp around 70-80 degrees, used a small amount of nutrients once. i am noticing on all my plants that the very bottom leafs are turning yellow. is this normal? is my pot to small for the plant? and i over watering? tell me what you think from my photos. thanks a ton

For the sake of keeping things moving I'll take a stab at trying to help.

@ 2 weeks I'd say yes they need bigger pots, plastic is easier to work with than pottery clay.

As they should not yet really need nutes, yet they look like yellowing from nitrogen defficiency, and you don't seem to be watching PH, I'd guess starting to lock out, PH may be low, acidic. You have pete soil, also acidic. Get a handle on the PH, Milwaukee has a yellow digital pen thing for like 20 bucks. General Hydroponics has a "kit" with up down and drops to test.

Curling leaves and yellow could also be over water, but soil looks dry on surface. The above two thing are a safe place to start.

They are root-cramped. That is the bottom line. Go up to at least a 1 gallon.

Add about 20-30% perlite with the next transplant... It's most likely rootbound, but hopefully you've solved that issue by now. How are they looking?
