Without a super clear picture of the tricomes it’s so hard to tell. Based on the 1st few pictures where I’m pretty positive I’m seeing a bunch of white pistols, I’d say you aren’t ready yet.
The tricomes are your tell. Aside from that, the plants look great!

I do it for one reason, not sure if it makes a difference in taste, at least I never noticed. The reason I do it is it is so much eaiser to final clean the buds without all thee shade leaves stuck to the buds which makes it a royal pain in the behind. long time ago I used to just dry them with all the leaves left on them, then tried it with a two trim method , all the big shade leaves when hanging them, then final trim when they are ready go go into cure jars.
Yeah, I remember reading all these warnings about how wet trimming ruins your scissors and how hard it is to keep everything clean so I did my first 3 harvests dry drim.
Then I actually tried wet trimming and it’s so much easier. Especially if you harvest your plants in parts (Top, Middle, Bottom) it’s even easier.
