I'm a week or 2 away from harvest and I saw this on one of my girls. I tried to look for pics of it online but couldn't find anything. does anyone know what this is on my leaf?

Anything that dark has an excessive amount of nitrogen, especially near harvest time. The crispy edges are indicative of overfertilization usually. Start flushing with pure water now. At least three times the volume of the container per flush.

possible Phosphorus deficiency, imo your fine just flush like they^ said at 3 to 4 x your volume.

yeah like they say your close to harvest i wouldnt worry so much. Looks to be one of the lower leaves anyway. depending on how long the strain runs is when i start my flush but thats just me. i wouldnt flush a 8 week strain for 2 weeks. i think you will be missing some critical peak bloom time with low nutes if you did.
