Sup dude,
I'm starting my first grow as well...check it out if you have a chance...
As far as your plants are growing they seem to be starting fine, you might have a little bit of nute burn, indicated by the yellow tips of your leaves...that's probably because you're using miracle grow...you might want to think about transferring your plant to a larger pot with a different soil (foxfarm is good, but generally an organic soil with no fertilizers is best so you can control that)...just some advice from a fellow beginner...dont worry, i'm using miracle grow to right now and I'm gonna try to switch in a week to larger 5 gall pots...it provides more room for the tap root and makes the plant nice and strong...:rastasmoke:
Best!
