first grow how close am I to chopping down

This is my first grow. Do not know strain but believe it to be sativa. Two plants different strains. So most of my pistil are brown and trichomes are mostly milky. One plant the leaves are getting lighter vary quickly. any tips and suggestions are vary welcomed.

3-4 weeks

But looking good

Thank you, I cloned off these after they where in flowering stage. I don't know if I'll have the room to keep vegging that long.

Yeah looks good for a first grow!!
Reminds me a bit of blue dream I'd say another 2 weeks minimum
