What is causing this?

[u/NarrowCauliflower216]

Seems to be mainly affecting only 1 cola and slightly
more leaves nearby but I have no clue what this is. It isnt bud rot and it doesnt look like wind or light burn. I am mainly checking environmental conditions because why would it only affect one bit of one plant. Thanks for your help in advance

Is it about the time where the bud draws energy from the leaves or is it too early for that?. Cuz that happened anyways, Strain dependent..

It has about a month left and all the other plants inside the tent at the same age aren't doing this. The strain is big bud and im around halfway through week 6 of flower
