Alright here we go again. Ran in to some troubles with the light, it seems there is some fault in the wiring somewhere, when the psu is running the light emitt a small amount of light. It seems to be enough to keep the plants from flowering. Right now i solved by only having the fans running...
No signs of flowers yet. The grills look alot more happy right now, i dont know what i did wrong in the start, maybe underfeeding? Raised the ppm to 1500 day 23 and they seem to like it. They're starting to fill out the box nicely, still have alot of room height wise.
So happy i've rid myself...
