out of 5 this is the only one having the issue. i want to make a special batch of food for her to straighten the issue out. ive been giving her extra cal mag with the bloom nutes instead of the additional stuff i mix in...
im in coco, my pH in is consistent @5.8, my EC in is consistent at 1500-1600....runoff varies plant to plant but issue plant runoff EC is 1900. so why is my girl lookin so rough? started at this on a few ....

became this

should i blast her w more calmag? continue feeding as normal? only the canopy is rly effected so far..should i flush?
Looks like light burn. What light you use and how close is it?
I agree, looks to me. Light burn.
interesting....the light is a spider farm sf2000 at 13" 80% strength. ive taken a lot of precautions to prevent light burn (had it happen last grow) so im surprised by both of you saying it may be that....!
i will lower the strength of the light to 50% since i cant raise the light anymore! thank you brandon and mrG
You need to be about 20” away I would definitely say light burn
