salt/nute residue V.S. powdery mildew

So I noticed these white spots ended up near leaf tips about 2 days after I foliar sprayed Epsom salts & 0-0-50 K nutrients mixed with water. Given their uniform location & appearance I assume nute residue?

yup thats just residue

Spray must of been on the strong side, I'd spray that shit off with some plain water, let it rain but dim that led before hand lol.

Cool, yea i sprayed it down 3 days in a row, it's already been on there for a week, I just noticed it yesterday. So whatever damage is probably already done. I will try to spray it off though, thanks guys!

What are you feeding and what medium? Something is up with that plant that Epsom salts and boosters won't fix lol these plants need healthy foliage to grow nice buds.

FFOF
First top dress was 5tbsp of 4-6-3 at flip
+ 3 handfuls FFOF on top
Second top dress Gaia Green Flower 5tbsp
+ 2 handfuls of fresh FFOF on top
Also some Fish & Kelp watered in to soil... 1tbsp, once a week. Then the foliar with Epsom & K once.

That's it. Yea pretty much all the fan leaves below the bud sites are donezo.

Strip away the dead leaves, that's asking for trouble , half faded ones are okay.

I see residue and nute burn? Your soil looks to be hot

Looks possibly like nute burn... especially if you've been adding dry and that N filled fish stuff on top. Could be a multitude of causes too though. If you're going to go soil, IMO go a big pot for flower so you have plenty nutes provided by the soil instead of trying to dress up a smaller pot.
