Diagnosis needed

Hello people, good to be here. I have noticed some markings on my girl. I haven't started feeding yet so I'm hoping its a deficiency. May be pests though because ventilation isn't on point. Leaves have been dropping more than I've ever noticed but I don't know much so would be grateful for some help. Thanks in advance

Also if it is a deficiency, could I just pot up to solve this instead of using feed? I had to water today and I have a feeling it'll be bad to water her again so soon?

This is the top of her btw, might help in factoring things in

Got a cat?

Nope. I do not have ventilation though. Does this seem like an infestation? She's on week 5 now.

I’m on my first grow as well. I will say, those look very similar to the beginning of my thrips infestation.The first thing I noticed were the little “bites”. I would check up and down all around bc thrips are small and hard to see. They’re like rice, way smaller. If not thrips, maybe another very small pest. It probably wouldn’t hurt to give a pest treatment (neem oil or something) just in case?

Maybe this is something? I have no clue.
