How Far Into Flowering Am I?

How far along does it look like i am. I havent really been keeping track and just started feeding them bloombastic. im wondering when the buds are gonna start swelling so the hairs are less visible. This is my 1st grow under a 400 watt in ffof soil also just added co2 to the room yesterday hoping that will help out towards the end of my grow. Pictures of co2 setup below; im going to redo the co2 setup next grow it just turned out like this because of how little tubing the regulator came with and i don't want to have to go get more so i just made do with what i had.

and if anyone could estimate how much you think these plants will produce that would be cool too

Looks like your around 4 weeks of flower...

Nobody will be able to accurately tell you how far into flowering you are since they have no idea what your strain is, even then they would have to be familiar with that particular strain and know what it looks like throughout it, but just looking at the buds you appear to have a good 2-3 weeks left, maybe a little bit more. You should have some more resin production and get a 30x microscope thingy to look at your trich's, once they start turning from cloudy to amber you can chop away

alright and also they aren't smelling strong at all and the little smell they do have isn't a good smell. The strain is ak-47 if that makes any difference

ok you have a long ass way to go. Be patient. Id say you are 2-3 weeks in, leaving 6-12 weeks left. Ya id could be as long as 12 or more , keep it healthy as possible the whole way
