dude lol i just was checking out an NFT grow with the same-ish question, right now with three plants that size you can expect anywhere from 250 to 450 gs , but if you wait until you see some kind of vegetative stretch (like a week or two more) where your plants "double" in size , then you can expect much more like 350 to 650 in the same space for a few weeks extra veg. the main idea is filling up your scrog net fully then flipping and maybe using a second layer of scrog netting to optimise.
basically you need these extra weeks of veg from the topping and LST that's been done, ultimately the decision is yours , though! hope this helps ! 🚀
