I will paypal you ¥13.75 to never ask such a dumb question again.
259 grams.
You should do better than that with a 600, shame on you.
Because you lost so much floor space to your fan and wood frame (for a scrog, I assume?) you won’t break 10 oz, in my opinion. You should be able to pull at least 12 in the future, run 4 plants next time, drill some holes in the base of that fan and hang it from the tent frame to regain floor space and clean up in there, it sort of looks messy and filthy. Cleanliness is next to Dankness.
And nobody can guess your yield this early in flower, not with any reliable results.
