How close to harvesting

I just wanted to see how close I am to harvest, this is my first grow
Plant 1






Plant 2





Plant 3




Plant 4




Plant 5



Looks like 3 to 4 weeks to go.

Yeah still got another couple weeks.
Almost there tho, good job :+1:

Should I be worried about these 2 plants the buds look like they are turning brown





I see a lot of clear
I vote give the plant more time.
