Yellow Tips - Epson salt? +REP to U

Heya, I've had yellow tips on only 1 of my plants...not sure why. They've been yellow for 2+ weeks, other than that...it seems just fine so I havent adjusted anything. But can't I add some Salt? If so, how much per gallon of water? (DWC in 5gal bucket)

THANKS ALOT EVERYONE

Idk man, for less than $15 you can get a bottle of Calmag. I think I'd go that route, before adding epsoms to hydro. Soil's much safer, in that respect.

I'm sure you can use epsoms in your setup, sparingly, but idk the amounts, so can't suggest anything. If it's your only option, hopefully someone will see this and help you out.

same thing for me but ime in soil used calmag and its gone

adding stuff might make it worse?

^Addng too much, is what I was worried about.
