how long is left?

hello i am looking to cut these down in 6 days are they ready they are 9 weeks into flower i do not know what the strain is hear are so pics

You got a lot of white pistils there looks like you got some time left idk about 6 days.Maybe 2-3 weeks looks like sativa.

thanks. Do you think the buds would get much bigger or just ripen?

I presume they will do both

lol what i mean will it make a big difference in the yield or would i only loose out on a gram or 2?

Again, don't look at the pistils to determine harvest. You must look at the trichomes. If they are mostly cloudy or 10% amber rest cloudy, harvest it now. Every single pistil that is white when harvested will turn amber after harvest. Do NOT rely on them to determine harvest time. They are highly strain dependent on if they change while growing or after. They contain NO thc/cbn/cbd.
