First Hydro set up, 2 strains. Tell me what you think

So this is my first Hydroponics grow, I went with flood and drain. 20 gallon res, 2*4 table. Currently using 212 watt t5 for veg. I have Pineapple Express, and SFV OG. The PE is 2 weeks 2 days from being planted, and the sfv og 2 1/2 weeks since they been transplanted. Using CNS17 Grow and bloom along with sweet raw from botnicare. And silica from mad farmer. Feeding 4 times a day. Let me know what y'all think!!!!! Pineapple in rockwool, SFV in clay pebbles.

I started off a bit late but I will be posting more as they grow. The pineapple express was planted by seed and the sfv were clones. I have an inline fan sucking out the hot air as it gets way hot in my room. The plants are in a 5*5 gorilla grow tent, the tent in my bedroom. I have a co2 bag instead of a tank.
