Are you growing outside ? They will not yield you a p each. I have indicas atleast 3 times bigger and I'm not expecting a pound off each, not even a half. Depends on many things, how bushy how many tops if you lst or super crop how healthy the plant has been if it ever got stunned, the nutes, the ph of water, size of pot, amount of sunlight, humidity. A million factors come into this and it is always hard to say.
you have a nice garden - don't worry about how much each one will give you worry about how healthy each one is. looks like you'll have plenty o smoke. you'd be surprised at how much growth we have left yet
half are in 30-45 gal pots the rest are in 7 gal total 62 since its been cloudy some have begin to go into flower im goin to hit them hard with veg nuits to try and reverse the flowering
