Nut burn? Not sure what this is

This was on the bottom of my autoflower… a couple have been popping up but the rest of the plant looks fine. Any advice? Ph is between 5.8 and 6.5 every water I try to keep it around 6.1 and 6.3. They get Bergman nuts every other watering.

Its not unusual for lower leaves to yellow and die.
Pic of the whole plant would help.
How old is the plant?


I’m a total newb, but how old is the plant? I pick dying leaves off the lower portion of my plants all the time.

It’s a 6 week old autoflower already in bloom.

I wouldnt worry about a couple dying leaves on the bottom at that age.
If you want further info beyond that we will need more pics of the whole plant and some info on the specifics of your grow.
Lots of helpful people here, dont be shy.
Hope your grow goes well.
