how far away should and led/qb be from the plant?

That makes sense, since I'm feeding them like the ones under my 1k hps. Also they are autos which I've never grown before, only photos in my past.

Mine is a total experiment that I'm doing in my veg tent to see how they work. In coco, which I have grown in for 10 years, battling cal and mag deficiencies by doubling up on cal mag which has N in it. Then top dressed with dolomite lime and got that (mostly) under control and just backed off the cal mag this week, so it all makes sense to me now, lol. Thanks man!!

Man it's a learning experience. Think I'll switch to organic soil when I swap my 1k hps se for 2 of the 320 watt 324 xl's in the flower room. Order is already in for the second light.

I use the hlg 260xl and I keep my light about 12" away from my plants and I haven't had any light burn issues.

That plant was grown in a 60 cm x 60 cm space. Light was dimmed to about %50 during seedling and early veg stages and was ramped up to %100 (135 watts) for flower.
