It’s really something I’d like to give you an answer to but it’s all a guess based on assumptions without knowing enough about your skill, background, etc. So many variables can affect your final dry harvest weight. I generally look at total footprint of grow and how full that canopy is, light input, environmental, etc .
For you, I would safely say 1.25-2oz per plant, dried, based on one photo I see of two plants on your kitchen counter (nice kitchen btw)
Things like letting your bud get rock hard/dense and fatten up will have huge impacts on final weight. Resist the urge to harvest early. Remember that dried flower can “shrink” to less than half the size of live colas. It sucks when you chop early and end up with airy colas. If your breeder says 8 weeks go with 9. Watch The trichomes of course.
Tendency is for people to harvest early when the buds are not dense, and by the time it’s dried you have an underwhelming final weight.
I hope you hit a higher number than what I’m projecting, as it’s better to set a low expectation and exceed it. Remember once you chop you are only beginning the next stage of drying and curing. Low and slow. Colder temps and longer dry times are your friend for a higher quality finished product. Have a plan and system in place prior to chop so you;re not spinning wheels T that critical time figuring out your drying process.
Cheers
