So the LED I bought is a HLG-300L RSPEC. Apparently it’s a good one. I’ve tried changing its height to no avail. I also have been using an organic calcium/magnesium additive. Again no change. I use an organic soil mix from a very well k own organic grower. The only thing I changed was the light. Seedlings will start to show problems after a few weeks and it continues through veg. Once they go into flower with a HPS everything gets better until harvest.

I’ve read that with the R-Spec HLG LEDs plants tend to grow tall and stretchy in the vegetative stage due to the high amounts of red in the spectrum. However, that can be controlled with plant training like bending the stems over and tying them down. If you’re looking to produce the highest THC in your buds as possible, it’s worth the extra care.
