Banana or anything else?

Honestly looks like a calyx forming on top, possibly beginning of foxtailing? But as other had mentioned hard to see. Personally never had nanners form on the top of the bud, they always popped up middle to bottom of buds, and lower growth. If it starts to resemble a nanner in any way I'd pluck it for better examination. Good luck growmie

As the other grower said, it is hard to see. I experienced bananas in my last grow and I am still unsure what caused them. Could be all manor of things like too much feed, VPD not correct, pH of you substrate, temperature of your substrate. It could just be genetics and part of this pheno, that I am unsure of. You dealt with it the same as I and I didn't have any issues with my buds except the immediate area where the bananas were. I hope this helps in some way. Good luck

Sorry, I can't, unfortunately, I already took it out as a precaution, also I will have taken about 10 photos and that was the best

Would you be able to get a better clearer picture?
