Wind burn?

overnight some of my plants leaves started to canoe and turn whitish yellow. Any idea what can cause this? It was pretty windy yesterday the plant was blowing around pretty good could this have something to do with it?

Have they been outside the whole time or did you just move them recently? That happened overnight? Looks like sun burn.

Yea it was the first day outside. Seemed to happen overnight. It does favor one side of the plant, the side most exposed to the sun. Any suggestions?

When you move a plant, any plant, out side from in you have to harden them off to the increase light intensity. Put them in a shaded location and slowly acclimate the leaves to the sun first with morning sun then half day then full sun over the course of a week or two. Basically the leaves need to develop a cuticle layer to protect them from the higher overall intensity and the UV radiation. An average sunny day is around 100k lux. The bleached leaves will never recover but I would leave them on till the new growth takes over. parts of them may still be producing sugars.

Thanks for the help!! Will the leaves that are slightly burned ultimately die too? It was praying to the sun all day today and looked healthy besides the above mentioned problem. Hoping I don’t wake up to a dead plant tomorrow morning.

Sunburn won’t kill her. The leaves that are damaged may just stay that silver color or go brown. Either way she will produce new leaves. Don’t sweat it.

Wind burn is a relatively new term to cannabis. Wind doesn't burn your plants. If it did then outdoor growers in Oregon and California would have a bunch of burned up plants. Because get guess what we get in these areas, Wind. I don't know how these myths spread in the cannabis realm but it's like much of the stuff out there. Probably started from some dude on youtube.

Wind burn does occur on some plants and trees. Evergreen trees and shrubs can be damaged by wind during cold months but you're plants are NOT going to be burned by the wind on a windy day. They might be damaged, broken branches, falling over, etc... But some wind isn't going to BURN your plants.

I agree with @Merlin1147 that the damage was due to moving your plants outside into the sun from inside. But it also depends on what type of light you're using inside. I put plants outside in the sun all the time weather permitting and have never experienced sunburn. That's from going from under HO T5's to outside. If you were using inexpensive LED's the plants probably were not used to the light intensity.
