Does this look like a potassium deficiency to you?

see the tips



or is this a nutrient burn? I have not fed these plants anything since June 11th.

Looks like nute burn. When did it show up? And is it getting worse? Other than that issue they look good.

if you look at the tips o the other leaves, you'll see it's present there as well, albeit not to the same extent as this one. this one actually looks fried on the very end, the other ones only yellowed slightly on the very end of the leaf.

the burnt/fried tip depicted in the photo only showed up today. I'd say it's getting worse

Not unless it develops a potassium deficiency

They look fine to me. I don't suggest feeding it anything for a while. Even though you might have fed it nearly a month ago, a nitrogen burn can be delayed because of slow-release fertilizers.

Have you thought about testing the pH of the soil?

Overwatering will cause potassium deficiency look as well, I don’t believe you have this tho. Plant looks good. No stress

That looks like a little nutrient burn, if you’ve not been feeding then good keep doing that for now, what were you feeding and how much?

I’ll cast my vote for nute burn over K deficiency.
