Bud and crystalizing!

Hello, this is my first grow roughlty what size should a bud be at 4 weeks flowering and when should you start seeing crystals?
Thanks any help would be apprichiated!!!

Should be seeing crystals forming 4 weeks into flowering. Buds are prominent but sparse.

Well If you are 4 weeks in you should start seeing crystals forming pretty soon if not yet.

There's a lot of factors that go into this...if you are growing correctly I would say around 4 weeks you would see Trich production. As for size, that completely depends how big your plants are, lights used, EVERYTHING. No one can tell you what size your buds will be except for yourself.
