And this is the size of my box:

You can see the AC fan attached at the top corner; it blows down directly onto the plant

So here is my plant now:
[attachment=o229085]

I've watered with new solution (pure blend pro) Grow:LQ=3mL:2.5mL and added some molasses to the mix and sprayed with some epsom salt solution on the leaves and then I'm gonna rinse it off with a fresh water rinse afterwards.

The plant is growing fine, it's actually kind of good growth but there's just kind of wavy leaves and yellow patches and random chlorosis on the new leaves.
