1000 Watt 4x4 Waterfarm/Soil GDP

Hello, everyone! This is my first grow.

My setup is;

Hydrohut - Silver Edition Hut 4.5X4.5
Continental Fan In-Line Duct Fan 6 Inch, 308 CFM
Can-Lite Carbon Filter 6 inch - 600 CFM
Two Clip on Hurricane Fans
600W MH - Apollo / 1000W HPS Eye Hortilux
600W/1000w Quantum dimmable ballasts
BlockBuster 6 in Air-Cooled Reflector
2x Converted Waterfarm (Air stones running in both reservoirs)
Two 7 gallon smart pots
General Hydroponics Flora Series
Botanicare Hydroguard
Apera P.H. meter
HM ppm meter

The strain I will be running is GDP(clones);

I plan on running 4 clones in the 4x4 tent. Two will be in 7 gallon smart pots and two in waterfarms (If all goes right the size of the plants in the waterfarms should be significantly larger, which i hope to manage with proper LST and Toping). Ill be using a 600w MH for the veg stage and a 1000w HPS for flowering.

Watered and drained/topped off waterfarms.

LST, topped, defoiled slightly.

Day 12 since clones entered room.

Day 14. Roots are showing from the bottom of the containers! Notice how the plant on the left is larger. This is because I planted the rockwool cube closer to the drip ring so it was getting constantly fed. The girl on the left was planted in the middle. I've had to hand water both daily.

Day 18. Transplanted. Changed res. Topped. Slightly defoiled. Added panda plastic.

open to any suggestions. Specifically how to deal with the larger plants in the water farm's.

Id reccomend top or FIM and LST the big plants also put up a trellis it keeps your canopy nice & even..
