Strain: Grape Ape. Fem, Sativa, outdoors in greenhouse.

What is happening here? I’m new, very new.

First of all, welcome to the community @WolfWriter . To determine this accurately, we would need a bit more information about the grow.
How often do you water, with what, which fertilizer and how often / how much, temperature, humidity.,…
A few better pictures, close-ups of the affected areas.
At first glance I would guess a phosphorus deficiency, possibly also a magnesium deficiency. To be able to judge this better, more info would be good.
Tell us as much as possible about what you give them and what the conditions are like, and take a few more good close-ups, then we can help you better.
