We are in the last week of white widow autoflower flowering. There seems to be an issue with either light burn or Bud rot where the tips of the sugar leaves are appearing brown.
Attached is a picture. Is this Bud rat or light burn?
We have lowered the light intensity from 100 to 75%. We have raised the VPD target. If this is bud rot, what needs to be done immediately?
Thanks guys and Happy 
Day!!
How long has it been in flower and what is the light schedule?
I can’t see any bud rot in the pictures and the brown curly leaves are not bud rot. Bud rot will be in the buds as a dark brown spot
I also see that some of the tips of your leaves are curled in and look brown I think this maybe a nute problem i could be wrong I’m new to growing so I’m not to sure @Gl1tch @Storm @OGIncognito @Lostgirl
You have a pH or PPM problem. What is your runoff pH, PPM, what soil are you growing in, and what product(s) are you feeding the plant?
It’s not bud rot and I don’t think I’ve ever seen a legitimate case of light burn in the 5 years I’ve been here in the forum. The only way a light is going to burn a plant is if the heat from the light damages the plant from a light being placed too close to the plant’s canopy.
