Should I remove this yellowing growth? Week 4 of flower.

You can get rid of them, I actually do a final defoliation around this time and it's very beneficial to your plant and will definitely help your flowers swell where you want them to 😉

A bit too late, you can use this for eatabels or bubble hash with rest of trim. 2-4 week of flower is still ok, later you just loose weight. Tested on multiple plants, second wave of clearing dont bring proffit at least by my observations. I was doing last big clearing at end of 5th or start of 6th, eventually dropped that way. Great grow you have, nice trees really. Unless you need better air movement - i would not trim them personally, would just plan how to use. Youll have many popcorns anyways. Good luck in finishing it !

Remove them! You do not want those small popcorn buds, you want them big fat juicy sticky buds! 😋

You can remove it or leave it. It's not going to make much difference either way. The way i see it, removing lower growth I personally don't believe it is of any benefit to the upper bud development. I like to leave the plants bud sites in tact, because even though they don't fill out to be pretty smokable bag appeal nugs, what they do lend themselves to is making bubble hash, alcohol/oil soluble edible material. Or just trim it, dry it, cure it, and grind it up and drop it in your vape. You'll get high off it i promise. Sometimes these modern day grower practices I think are just silly.

U can erase them if u want. They wont do much, typical popcorn buds. Plant will be fine with that, no harm would be done. Some folks says its still cost for plant to have them. Not that much cost to need cut them. Feel free with ur decision Bless
