Heat Stress, Or Over Nute?

The problem appeared to have started from the top down... have a few fans to regulate temp... What do you guys think? ppm meter is on the way...

looks like some nute burn, just flush it

What kind of Lights are you using?
How old are the plant(s)?
How much Nutes are you feeding it every feeding time?

250 MH light
880 ppms
just toping with h20
mild nutes every week ish?
