CAN YOU IDENTIFY THIS DEFICIENCY

This has been going on for about 3 weeks now and it progressing towards the canopy

any help to figure it out or anyone who can tell from the pics plz help

looks like a little nute burn to me, but I aint grown outdoors in years.

Can't say for sure but maybe a potash deficiency

Honestly, that looks more like a calcium deficiency to me.
What does the rest of the plant look like?

You need to put up more info if you want an answer. What soil? how often do you water? are you adding nutrients? what is the max outdoor temp? anything else you can think of?

The plants in the background (although blurred) have a generally healthy look to them. And the leaves in question seem to all be older fan leaves. And flowering has probably started too. So I would guess it to be the plants drawing from the older leaves to feed newer growth. It just happens. Unless the symptoms are widespread you really don't have anything to worry about. But just to be sure, please post some more pictures of the whole plant(s).
Good luck friend!

The rest is fine. It’s starting from the bottom inside up
