My First Grow! - Advice Welcome

So this is my first grow. It's a 8x6 cedar closet ( keep the bugs out). I am using a 65 galling resavoir ebb and flow titan. I also have an air line in every bucket, although I have eliminated air stones because I feel they hinder oxygen bubbles. There are 12 5 gallon pots, half with rockwool half with stones and or hydro pebbles. I have 2 chem 90 clones 3 strawberry diesel clones, 2 tangie, 3 gorilla glue, and 1 pineapple express. I am using 1 900w marshydro and 2 300w marshydro both LED.I also have a 40 watt led I Rotate on smaller or lower branches. I am weekly fiming, daily light defoliation, and I am lollipoping with some supercropping. 2 of my clones are also monster cropped. My Chem 90's are 2 weeks old, and the rest a month old. PH is 5.5, and ppm is at 900. Water temp is 71. Room temp ranges from 74-88. 30-65% humidity during veg( 20% during flower). I am using TX green solutions A and B for veg, and sensibud A and B During flower. I also use photosynthesis plus foliar spray weekly and nutrient uptake solution with hummus derived good bacteria. I also have one oscillating fan, and a humidifier.
