Hiya, folks.

Rookie outdoor casual grower. Got this that doesn't actually fit what I've seen described as nutrient burn...

Any clues?

Much appreciated

This is actually a deficiency;
the classic lack of Ca Mg.
Pick up a bottle of Procal and feed with it regularly.
Anything showing in partial inner sections of leaves in this form is abnormal and should be addressed.

Example of Ca Mg deficiency:

Bingo. Calcium Deficiency. And adding some Mg, probably wont hurt, if it isnt already getting some.

Always use a Ca Mg supplement when growing in containers, cannabis is a Ca hungry plant.

I very much appreciate your help and advice, folks!
Please excuse any clumsiness on my part, I'm not very techy (at all!) and tend ti fumble quite a bit, particularly when engaging with a new (unfamiliar)... platform (if that's the right word)

Calcium deficiency is possible, but I don't see much indication of magnesium deficiency, if any. So, there's a possible problem of the plant getting too much magnesium from the calmag, causing yet another problem.

It doesn't quite look like a calcium deficiency to me, but I can't say that it isn't. How close is this plant to other plants? What's the soil like? Is the plant in a pot or in the ground? Where are the affected leaves on the plant (i.e., high, low or everywhere)? How moist or dry is the soil?
