Looking good man. What is your PAR on the plants ? I would try and get them squatted down a bit closer if possible. IF you do not already have a PAR meter & a thermal heat gun I would get them ASAP. I recommend them to all growers it really allows you to maximize the potential of your lights. Keep it up & check out my diary and give me a follow if you get a second !
@OGbros, Hydro is amazingly simple for the flush. When I was medically producing for myself back in 2013 I had a undercurrent system I built myself with uni-seals and 5 gallon buckets. I had 2 8 plant systems under 4 HPS lights. For flush just run pure water for a week straight. Empty your reservoir and run low PPM water. Adjust PH accordingly depending on if you want to bring out color or not. High PH and low PH will bring out different ends of the color spectrum. Amino acids are good to feed during flush in hydro or soil. I also use Cane molasses all the way through the grow & through the flush too. This is something I picked up at the site in my diary so I cannot speak to its affectiveness in hydro. I am pretty sure my old videos are still on youtube of me as a young adult little whipper snapper jabbin on about my hydro setup lol, Oh how times change.
