1st Grow... Feedback?

Hi everyone, a few weeks into my first grow, I have 3 ladies are autos that are about 4 weeks old from when the seed was put into soil. The last two are smaller as they are only 2.5 weeks old and are photo strains.

Questions I have. We track how many days/weeks flower stage is, but how long is seedling and veg stages?

I have done a little bit of LST on the autos but am now doing only limited LST since they are so dense I had a lot of time getting things to tie off. Should I be pruning these large fan leaves out now? Trying to limit the amount of stress.

the Autos:
Gorilla Glue
Dream Berry
Purple Stilton

Critical Bilbo

Thanks in advance!

Welcome, looking good, keep up the great work.
