Don't care how old this is but those are not trichomes you are praying for a win but those are 100% THRIP EGGS. Thrip eggs will be bubbly looking and never have a long stem. Those don't have stem at all. Idk how you thought they were trichomes. Thrips lay eggs super hardcore fast and they typically spawn every 3-5 days depending on species. You need to constantly preventative maintenance once you've had thrips once. Spray plants down with Plant Therapy per instruction or Neem Oil or any of the recommended things. Never spray plants in mid/late flower if that becomes necessary throw the bud away and save lives.
