The rust spot is not likely a ph (absorbtion) issue but the tip of your ph meter should be about about 1/4 inch or so into whatever liquid you are testing. Get yourself a calibration solution to check it for accuracy.
Saw your other thread & thought that it looked like maybe you just spilled a little nute solution on the leaves but rust spots typically indicate a cal/mag deficiency. Usually the rust spots would occur on many of the leaves not just one or 2 so don’t go too crazy trying to fix it just yet.
If you have not been giving them cal/mag it’s probably time to do so but if you have been giving macros up to this point then I would hold off & see what happens over the next week or two before doing anything too drastic. I see there is a little burn at the tips from a previous mild toxicity so proceed with caution; sometimes when you give too much soluble NPK they need more macros in order to help to absorb everything else.

What kind of medium are you growing in?

Then you should be giving cal/mag at least weekly along with your bloom nutrient. That should help.

Depends on his water supply. Mine has enough Ca so I don't want to add much extra. My Mg does get low sometimes, but I've been using Langbeinite and Epsom to supplement. I've had issues with Ca toxicity and lockouts.

If there were to be issues with a lack of macros now in mid bloom is the time they would likely begin to show...dissolved Epsom salt works too but maybe see what’s what first. Give it a week...

Epsom has Mg and S, but no Ca. I agree that rust spots are typically from Ca deficiency, but I also agree that it doesn't look like that to me. It looks like he burned them a little. I'd also be curious about the Ph and what he's feeding and all that.
Sorry man. Not trying to correct you. I learn a lot from you.

Damn. That's a crazy potent chemical formula I think. Way too much K. That's probably your issue.

Okay ya I was feeding them every watering then I read on here water twice feed once which I've been doing but this last time I watered 3 times will feed next

You're feeding too much K is my guess. Get a different fertilizer. I'm in soil, but I don't use chemicals.

They are your plants. Do whatever you want; no idea what is in that but if it works for you go with it.
