Early Calcium Deficiency?

[waincox]

Does this look like possible early calcium deficiency? I use CalMag Plus 2x weekly with nutrients. I'm growing these indoors in 3 gal fabric pots with Ocean Forest soil however, I did mix in ~1/3 Roots Organics coco/perlite. I hear a lot against mixing coco & soil but I like the added drainage.

Doubt it’s a deficiency if your adding cal twice a week. Could be a uptake issue due to ph imbalance or bad transportation.
Are you checking ph and ec going in and coming out?

that looks nothing like cal def, and looks more like a wind burn issue to me.

Thanks for the input @4plant and @LittleDabbie my pH is getting a little high and my fan was too high a couple of weeks ago which could explain why it's on older leaves. Other than those few spots the plants are kicking ass. Again much appreciated.
