Help needed before its too late

im growing outdoor a local sativa strain…
a couple of days ago i started noticing that some leaves are becoming yellow… and some leaves are looking as in the attached photos while other leaves look very healthy and ok…
what do you think about this guys is it deficiency or over feeding??
im using NPK and adding compost once weekly…

so shall i flush the pot or just stop the nutes for a couple of weeks?

I would flush and follow with a week of straight water.

thx a lot dude… ill try that
peace

No problem… best of luck!

I’ve got something similar on a couple indoor plants, weird thing is they are light green on the tops… yet have some nute burn. Beyond me personally. That sort of nute burn isn’t too major, if it progresses then your in trouble and I’d flush like nuts, but a little bit of it is a good thing I think, like just the very very tips saying ok we’ve got just a miniscule amount too much
