First grow - Need advice

[crackpotman]

I started growing no too long ago with little to no knowledge of what I was doing. Nonetheless, I currently have 8 OG kush plants in their second week of flowering. They are in a hydroponic container (don't know specific name) and are growing in clay pebbles. I will link to pictures of the grow. I realize I am pretty far into the process but what im hoping to get out of posting here is to get any last minute advice that would still help and possibly boost my yield.

Any and all advice would be much appreciated! Thanks
