Problem with plant

[Qualabrown]

Woke up 2 days ago and this plant had turned this funny color

From pics looks like wind burn. But we'd need more info to figure it out. Medium? Nutes? Ph in and out? Lights? Anything about your set up or anything you might have changed.

Growing in Promix, using general hydroponics, ph in 6.0 somewhere between 5.0 and 5.5 out I'm using the drops to do Ph. 600 QB Led light.

Do you have a fan blowing directly on them?

Yeah but it moves this is the only like that out of 7 plants

Hey Qualabrown, if your PH is good, I'd give some Cal-Mag, or Epson salt if you are not already.
Those are some nice looking plants, by the way.
And welcome to GWE! !!!
Ps, what kind of plants are they ?
