This is a Blue Mystic plant from a 15 year old Nirvana fem seed. First month was iffy and a struggle then it took off. Just noticed the brown "burn" today. It's only on about 4-5 leaves towards the top of plant. Any help is much appreciated.

Looks like it may have dried back a bit too much doesn’t look bad.

May need to up your watering a bit.

That’s a good size plant for a small pot to go 3-4 days between watering imo.

Doesn’t look like nute burn to me

Thanks for the quick response. I will keep a closer eye on it. Last watering it was slightly wilted and bone dry. Not good in this weather. 90s most days... And I'm at altitude (6500 ft) so the sun is DIRECT

This is odd. It kind of looks like potassium, but if it were, all the lower leaves would have those symptoms, not just a could of leaves in the middle of the plant.

Maybe it's being scorched by the sun. Can you move the sun back a million miles?

That’ll do it. What’s above reflects below. That’s why it’s the top few leaves.
You had a little root death. Looks like your past it.
