Hey bro
Things are going pretty good. A couple of things that I've noticed looking back over your pictures. Number one I see a little bit of Sawtooth edges on your leaves that's kind of a temperature thing usually either heat stress from your lights being low or maybe stress from the light being too intense.
Sometimes a fan blowing across the top of the plant will solve that sometimes you want to back your light off a little bit it's just something to think about.
Number 2, you're right on the edge of nitrogen toxicity. You aren't there yet but you're very close. So at this point I recommend you back off the grow a little bit. Also, remember your micro has nitrogen in it and if you're using the GH Calimagic it will have nitrogen in it also.
Overall I think things look really good right now. Your plants probably don't look much different than mine at that stage and those adjustments I was talking about are exactly what I would do.
