Yellow tips?

My plant has had these yellow tips for a few weeks now. She is 3 weeks into flower. It really only affects the top growth and doesnt spread beyond the tips. Originally, it only occurred on the side nearest the fan, so I moved the fan up expecting it was some kind of wind burn. Now, it has spread to all top growth. She has plenty of micros and I just upped the P in case that was the problem. Her buds aren't fattening as much as my other girl, so P seemed like a good solution.

Temps, pH, and ppms are all solid. She's in a DWC bucket btw. Gorilla Glue Auto. 47 days old.

There is very little N. I switched to bloom nutes weeks ago.

doesn’t the darker green color mean a lot of nitrogen? ..plus the tips starting to burn adds to that suspicion

I'd second start of burn. Some of the nutrients may be in the soil still, reactivating when watered until the plant can actually use it all. Imo, keepy go, but can probably just use ph'd water for the next cycle or two, watching how they react.

I wouldnt be quick to dump in more P yet, as an abundance can create further problems.

Just an opinion, far from expert

Looking good though!
