Help, is this an issue

[GrowTheGreen]

So I noticed that this leaf is covered in weird spots and the edges are so dry that it just crumbles. Thought it might be just withering but I've never seen a leaf wither like that. Any ideas?

Looks like a disease to me. But then again so did the bumps on that hookers snatch last night but she promised me it wasn't

I use calmag 5ml per gallon from the first time I feed until mid flower then I stop.
