A question from a fellow grower: I’ve been growing the blueberry and pineapple together in a tent. I’ve cut buds off one by one thinking it was bud rot, but they were also close to the light and might just be burnt. Check out this picture. How can I tell if it’s bud rot?
If it’s bud rot it will be nasty inside. That does look rather burnt
Bud rot is brown and turns to power when you touch it how close to the lights are you plants
Here a few guides that should help you indentify bud rot
I’m thinking light burn it looks more crisp more the dusty, what lights are you using and we would need to know how far it’s from your Plant to be sure of its condition good luck .
