Ready to harvest?!?

After running through so many issues , I finally got to this stage in my 2x2, 3 indicas and 1 sativa. Its my first time harvesting any cannabis and I don’t know when is the best time toharbest and for how long should i flush. I will post pictures of the sativa in the comments. Please tell me how much more time these small nugs need

This is the sativa, It stretched a lot when i had cheap lights so its just popcorn nugs all over. All of the seeds are bag seeds btw

They all have a ways to go. The top one needs at least 2-3 weeks more. The lower sativa needs even longer. Be patient.

Thanks for the reply. So lets say i start flushing in 2 days for 10 days then add to that 2days of darkness, that should be enough, right?
