This didn't show up until after I had flushed, but was very, very minimal. So to be exact when it started, I can't say. I started flushing at week 8 of flower thinking I was going to harvest around week 10 but in reality had two - three more weeks to go. I tried to pick them off and they are still heartily attached to the plant instead of just falling off. None of my others have this issue which is kinda strange to me, they were all equally given the same nutes in the same amounts and vary sparingly as I don't like to use a lot of nutes and they all use the same soil. This is a mind bender! Yes, my buds are still growing that's why the fox tails (not from the lights or heat, just the way they are) and still bulking up. I plan to harvest in 1 to 2 weeks (week 12-13) or when I see amber trichomes start to appear, so I am getting close.
