Looks like deficiency of a few things but generally that occurs from either a lockout or severely underfeeding when so prolific. Do you know your drainage ph? What nutes and dose are you using? What is the water supply? What are your temps and rh like?
Mg deficiency (yellowing perimeter of leaves) Calcium deficiency looks like "rust spots", early signs of ca/mg deficiency are taco shaped leaves and upward curling of perimeter of leaves

Phosphorus deficiency (blotchy purplish coloring):
Potassium deficiency (like a burn around the edges of the leaf):
They look like 3-4 weeks in which is a time when most plants start to need heavier nutes and can start to transport nutrients from old growth prodigiously thus causing rapid necrosis. I've seen a few strains capable of sucking down leaves in a matter of hours.
