Growing in soil feeding with flora trio at half strength mars hydro 3000 for the light sitting about 24 inches awayTell us medium, feedings and lights. Type and distance.

Around 75 % I will post a update later on the girlsI have the Mars Hydro TSW 2000. My plants aren't much larger than yours. I keep the light at 75% brightness / 18 inches. Whether or not I am going too easy on my plants, I am not 100% certain right now.
I'm working with 300 true watts as opposed to your 450 though. That's a big difference. What do you have your brightness level set to?
