Hey first time grower here. Ive been having the ends of my bud hairs looking like they are dieing and shriveling. It doesnt seem to be mold and it isnt getting burnt from the light since there is buds close and far that are turning. I am having deficiency, looks to be calcium since the leaves arent good and i didnt fertilize properly at the start or i think i made the water to acidic since i just got my ph pen. The plant that the leaves look ok this problem is just starting. I also did just start using a dehumidifier. Sent from my SM-G950W using Grasscity Forum mobile app
If that discolored sugar leaf turned yellow overnight and can easily be pulled out, spread the bud apart at that spot and you'll know if you have bud rot. Unless it's really advanced you can't see it without looking inside the bud. Good luck.
No not bud rot as you haven't got buds yet! You do have some bad deficiency though which looks like cal or phosphorus
