Hi there!
The final yield is really hard to tell but one simple rule is this: Good grow with HPS is 1g/W and with LED 2g/W
From the looks of the plant I'd say that if she will grow happily till the end you might get that 150g's depending on the light you have.
Get your light a bit closer... You will increase your yield.. 12-13" inches.. expect an increase in transportation from the increase in photons.. But your light is a touch bit too high.. you'd be amazing at what a difference 2 inches can make just ask my old lady 😁
Looking awesome, seems like it's still needing a lot of fattening up. That plant might be up to 800 grams wet (cutting whole plant from the main stem) and 200 gr dry/cured sounds all right.
