Dinafem 4 Strain Grow

Hi everyone, so this week has been frustrating to say the least. I started off early this week which what looks to me as a potassium deficiency on the bubba kush and cheese. i ended up flushing and giving a good dose of nutrients with pk booster which seems to have stopped the spread. i noticed 2 days ago the bubba kush and cheese pushing out a few nanners which sucks so much. i have never had nanners before and im keeping my fingers crossed that they are sterile. i have 2 and half weeks to go so im praying they dont produce seeds. i think the deficiency is what stressed them. i am plucking them with tweezers as i see them which hasnt been much but crappy none the less.
