You should be able to answer this please if u can spare a minuteSorry, but I have to add a couple of thoughts here:
I think that notion that plants grown under LEDs need more Ca/Mg is an urban legend.
After coco coir gets saturated with Ca/Mg it doesn't need more "all the time."
What's my girl need more off I went a day late on feeds and she had few like this on bottom
