Anybody know what this is?

I have a plant that’s been growing indoors pretty well. It’s in it’s 3 or 4 week of flower. Recently with the new weather I’ve been sitting it outside to get natural light instead and to save on power. I’ve noticed a difference in the buds I think most immediately. But I’ve also noticed something start happening to the leaves. I am about 4 days into this routine.

Also to combat gnats and flies I added garlic and black pepper to my soil. Did that hurt me?

Any ideas?

Need to know your light indoors, grow medium, watering schedule and nutrients used, and nutrient EC(ppm)/pH

First glance looks like K deficient

FFOF soil and nutes. Idk the measurements. I do 2 big squirts of both Tiger Bloom and Big Bloom, less is more, every other week or so and a small bit of Cal-Mag

600 W LED light indoors

I water every week but even more now that they’ve been going outside and do the nutes every other week optimally

pH is also unknown

For more clarification, the leaf problems just started happening upon introduction to outside which leads me to believe it’s sun related
