i Pretty much get the same thing too people are busy and stuff but your grow looks pretty cool ill be watching. lower leaves slowly turning yellow generally means nitro deficiency. and your plants look a little older than 2.5 weeks is that from when you put the seed in the ground or once you had leaves? i say it looks like they needed the nitro to me. plants look good now. well ill be stopping in all the time you should stop by mine (first grow. led) maybe we can be posting buddies lol.

peace.
