Looks great! I've had good success with Producers, cropping out 2 Lbs per harvest. The added air pump is a great idea. You should also add one more thing to your box to really help your roots.. Liquid H2O2. Get the 29% strength and add 35ml every 3 days. Your roots will be super white, and as they grow and somewhat "sag" under their nets and get all tangled among the other plants, it'll provide oxygen to the dead spots the airstones still miss a little bit.
The last photos where you had your res filled with water showing the roots under the pots -- you need to add 1" of water to that. You want water almost touching the bottom of the nets, but about 1/2" back from that. It'll help you get more roots out the sides of the nets rather than just from the bottom of them.
Other than that, good luck, stick with Indicas, and dont really bother topping the plants, the canopy will be super full already. You shouldnt have to do any leaf trimming either since you have the upgraded flouros under the plants.
