SSSC - Purple OG Punch Automatic

I don't think it's lock out as that usually starts with leaching of color and your leaves are quite dark. Your ppm is pretty high for this early in bloom so yeah I'd say nutrient burn for sure. You have some clawing and dark coloration along with the damage. Tell take signs. Hope this helps.

Nice and frosty, but I'd leave it another bit. There's alot of clear in the pics of the trichomes, alot are cloudy also but I only see a few Ambers You will always see a few dotted around that are amber as the plant is ripening, but really that's got another week or so before all of them are fully milky and a few more have turned amber. But each to thier own mate.
