Nute Burn or Light Stress?

Am I pushing them too much or if the brown rust spots are from light stress? Seems to only be on the top half of them and showed up right when the stretch slowed/stopped. Week 8 at flowering~600 PAR from viparspectra KS5000 across the canopy.

Sorry, any idea about my plants? Is it light burn or nute burn? Thank you very much.

Those look more like week 4 or 5 flowering plants to me from the size of the buds that should be colas by now unless that's a 14 week strain like Cali Mist. What is the stated flowering period for those if you know that?

The damage seems more like something got on the leaves tho if sprays are used the damage is more a tan colour like that one leaf with the tan line down the middle.

It doesn't look widespread so not a panic but more info about media and what you're feeding them would help.

Not horribly wrong but it might be helpful to tell him that he can hit Report and request that his thread be moved over to Marijuana Plant Problems.

Not like he's posting tRumps latest hysterics in here.

If it was his first time posting in a wrong area, maybe, but it’s not.
