Burning from over feeding.
Nothing to do with calcium.

What nutrient deficiency is this?What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.
