First time aero grow

Ok this is my first time aero grow and it seems a little harder to grow than soil. My ph is at around 5.8 and Tds is 400ppm at the moment. Just put the clones in a couple of days ago.
Using a Aeroflo2-60 but only using 30 sites to spce the girls out a bit. The nutes are GH and using at almost 1/4 strength. Airation via 10in stone.
Lighting is 1000 watt MH and a 400 watt LED.
Cooling the water with a water chiller to 65 deg and using 2 400 cfm inline fans to exchange fresh air to the room.
Room temp is around 84 deg, Hot as shit summer this year around 110 deg at times so it hard to keep things cool.
Inclosed are some pics if anyone cares to help it would be greatly appreciated.Here are some of my clones I use in my outdoor grow.

do every other site next time.. build a cloner also, and a vegger
