Brother, take a step back and :smile:.
This is your first run, you are doing really well. No they are not huge ass montsters right now, but they look totally fine to me. I'll try help and suggest some things for you; the watering-you are feeding 1 gallon per plant every other day? That seems like a lot to me, for example I'm using a 2 gallon pot and feed 1 litre of water every 3-4 days. You could be overwatering a touch, which could mean your soil is on the acidic side. Second, how often and what strength are you feeding? The look like they would enjoy a little more Nitrogen and maybe at this point a touch of Calcium/Magnesuim, that will really help them green up and hold of any def which would usually be arising under LED at this point in your grow.
My third and final piece of advice is to chill bro! Believe it or not your plants feed off their surroundings and YOU. Be positive, look at what you have achieved so far and build on it. Feed them good karma bro and they will reward you. 2oz off each plant...who knows, I just pulled an oz from a 1ltr container grow, go figure.
Folk are looking and watching friend. They look great, people wont' really chime in here if there is nothing to chime in about! Once they get their funk on, and you have some nice buddage to show off, peeps will be looking and commenting. :niceshot:
