Indoor Leaf Symptoms--- NEED HELP!!

[abominableSCOTT]

Hi Guys, my Dad and I need help with our plants. A new strange symptom popped up on the leaves that we cant quite pin down. Plants are 21 days into flower in a greenhouse with an LED light on a timer. Plants are being fed Tiger Bloom twice a week with CalMag in coco.

Without much detail looks like mag deficiencies. Post in the infirmary and give all the details. Lights, nutes dose, ph, soil etc etc. Led lights demand magnesium.
