Has she been flushed bro? I wouldn't worry to much about the lower leave as she is well into bloom and shouldn't take to much longer?

All organic TaNg, but did do a mini flush 2 weeks ago (3-4gal in 5 gal pot) but everything was fine Ph (6.3) and color of run off was normal not extra dark.

Thank you BTW for chiming in! I appreciate it, must be getting a lil over worry some considering harvest is about 2.5 weeks out
