I run my light at 50% with a distance at about 24" during early veg. I run at about 18" and at 75% in what I consider mid veg and then 100% during flower. Light distance during flower start at about 12"-18" and I don't raise them again until flowers are about 6"-8" from the light. I allow the flowers to grow into the light.Do you ever turn your lights up 100% during veg? I’ve just turned up to 75% at the beginning of my second week of veg. Just now becoming familiar with the light and the plants response
I have a lux meter that I used in the beginning. I don't use it now because I know my light. I think you'll find these light distances and settings to be fairly close to what you want for the different stages of growth.
