It's not calmag to my eye... it's a zinc deficiency... you solve this by getting your PH down a notch to between 6.2 and 6.5... It can be absorbed at 6.0 but then you run into the situation that phosphorus won't be absorbed as IT needs a minimum of 6.2... Your affected leaves will not get any better but the newer ones should show no signs of the deficiency... Good luck

It’s on day 50 of flower and has been getting lighter leaves overall this week. It’s supposed to flower 50-60 days, according to the breeder.

What could have caused this to happen? Leaves are bending and middle pice of the leaves start to have a little yellowish tint (very lightly) if I can see it correctly. Overwatered or a nute-deficiency?
