Hello Chronic_Benji, your girls looking good and healthy.
You can remove the popcorn buds if you want to to see if it still going to make a change for your upper bud development.
If your not sure or want to test it, remove the popcorn just from 1 or 2 plants as comperison to the other ones.
My tip for next growth is to make sure after defoliating in week 3 of flower you check after a few days if you didnt miss a spot.
Thats to my knowledge the best time to do it and remove small buds who have no chance at all, so it will destribute the energy to the rest of the bud formation.
I hope this was an helpfull answer, Keep on growing my friend. Peace 😎👍
