Deficiency ?

It seem to .we much more a Light burn. Have you sprayed foliar lately? Or have you sprinkled something such as neem oil lately? With any doubt it is a burning, not a deficiency or an overfed. Don't worry. Just remove the leafs (I think they are the older fan leafs on the set, so it won't be a problem to defoliate a couple of burnt leafs. Keep managing a good grow. 420.

Just looks like the damage of the previous deficiency you asked about has died and dried. There is a bit of nute burn starting on the tips, so can dial back your feed, otherwise she looks fine.

pH of substrate, maybe? How frequently do you water? If you try to push that, let it dry a bit more between irrigations.

Not a phosphorous deficiency.............all the leaves would show symptons, not just a few.

Not a deficiency, but burning from over feeding or burning due to a build up of nutrient salts in the substrate...........or both.

Phosphorus deficiency possibly. Do you give pk ?
