Potassium deficiency clearly showing. This is cal mag window too 4-5 weeks into flower. You’re either lucky or calcium deficient with weak stems.

I think it’s calcium deficiency. I really didn’t (don’t) feed nutes.. I definitely could’ve (have been) not watering as much as I could’ve been.How should I treat cal mag deficiency??? Trying to get this first grow right!! I’ll water til I see run off. Thank you

Think they are running low for ph causing that. I believe they would do better of they got it up. Although we don't know what they are sitting in.

I see obvious potassium deficiency. In the single leaf pics it’s clearly showing. For whatever reason. pH or poor watering/feeding habits or something. So I’ll assume this plant is basically deficient at this stage of growth.

How do I fix?

Well if you haven’t fed a bloom feed I would start there. If it’s fortified soil it might not need everything but a single feeding isn’r going to induce toxicity. Aerate the medium really well. If it’s dry enough then feed it. Do you water by weight?
 
I have the same thing going on after flushing. Going to give it some fortified K water today. Been on pH balanced 7.0 rain and well water for a week but still get 5.7 or so on the run off.. But it is slowly getting worse. Mine started with burnt tips and now are on most leaf edges.

No. Not sure how that works? Please advise…
