how much will i yield from this grow and how much longer?

how much do you think these four plants will yield? and how much longer will it take? they've been flowering for about 5 weeks now under a 400w hps.

any comments, advise is much appreciated. thanks!

Nice plants......I predict 2 ounces.....probably a couple more weeks.....

only two ounces? how many more weeks do you think?

2 weeks are u fuckin kiddin me ur buds r just starting to develope, wait till ur pistols start degrading and turn orange or if u want u can look at at the resin glands and harvest wen they turn a amber color and 80% of the plant is mature.
