Need opinion please?!

anything from 1oz to 100 pounds but really there is no way of knowing not even guessing

Assuming it is a female, Jman23 is right

oh and i forgot to mention that it is 5-6 ft

size means nothing still could be an oz to 100 pounds depends on how well you taking care of it like giving all the nutes it need and all the sun it can get. are you outside?

yes it is out side about 8 hours of light its a gorilla grow. and it has nutes that are 4-4-4 just small amount but it look so healthy all the branches are about1/2 to 1 1/2 feet and its flowering no spots or anything just pure green.

Usually when trying to guesstimate I look at where my colas are and for each inch I figure I should get a gram at least... Not very accurate but it does help estimate a little. Once you have a couple harvests you can look at what your previous grams per watt was and that can help you guess as well if you are going under the same conditions. I should add this would be for indoors, not sure about outdoors sorry
