That single leaf tip?
Looks like insect damage more than burn to me. Fear the borg. (mites) Try using a magnifier to confirm before doing anything.

The first pic shows a lot of speckling over the majority of the leaf in the top left corner, I think your right, looks like mite damage.
@Kushheavy you need to look under the leaves with a magnifying glass mites are tiny. You also need to cut back on the N they are getting some N toxicity.

That’s strange… Mites travel pretty quickly I don’t see speckling but the photos aren’t very large. The leaf tip - is it crispy or is it powder like you describe? Can u wipe it off?

After another look I see quite a bit. Tips and then also some covering leaf surface… If no insects (mites or perhaps thrips from what I can see damage in the center of some leaves) What is ur feed like? Medium?
I use Canna Coco Nutrients so I’m assuming cutting back on N is using a low PPM on the A & B? Thanks for the feedback.

Coco/perlite medium…Canna Coco Nutrients…and yes it is like a powder that does smear when I wipe. A dusting of this is scattered throughout the plant…strange is none of my other plants are affected. I just used some flying insect Nukem and ordered Safe Dormant spray on all of my moms in case they are infected. Hopefully this will eradicate them.

Its like a powder that can smear…I had spider mites before and that showed white speckles…this brownish stuff is new for me.

Do you have a magnifier, something in 60x+ range? Take a sample from an affected leaf and check it. Only way to be sure.

Sounds to me like Powdery Mildew getting started.

Can’t see up close but cursory look suggests a couple burnt tips and maybe some dirt/water that got on the leaves and dried. It doesn’t look like mites or PM.
Looks like PM

Powdery mildews aren’t brown. It could be a rust fungus, Melampsora cannabina.
The treatments are similar, could try potassium bicarbonate; potassium silicate; 1:10 h20:ethanol mix; 1:1 milk:water mix; neem oil; suffoil; sulfer spray (not in flower and not within 2 weeks of an oil); or an H2O2 spray.
