Any idea of what this could be?

Little Gorilla Glue auto has some yellowing leaves.

just wondering if you may possibly know if it’s a specific Deficiency or what.
This plant also was a bit of a runt and didn’t get very big at all.
I had snapped the stem early on and I’m sure that slowed her down.
thanks!

Depending on how late it is in flower, some yellowing is to be expected as the plant nears it's predetermined death date. Autos are finicky eaters most of the time. They can sometimes eat monsterous amounts of nutrients, other times can barely handle any at all without showing burn. This however looks to be like it's Nitrogen is leaching and possibly a ph issue with the brown coming in the end. But if it's close to harvest, don't try to correct it, you'll probably jus mess it up more if you do.
