2ozs per plant

What can I try different?
I have 9 plants that veg for 9 weeks from 3" clones.
Diy drip system that recirculates. I run h.peroxide because I don't have air stones. They get in between 2-2.5ft in 9 weeks. They are under 6 4ft t5s in the white spectrum mounted horizontal. I use gH nutes that is about 8-9 parts, top off with fresh water and drain every 1-1.5 weeks. The water temp is a bad 83 deg avg because the constant power to pump. I run veg 24 hrs so they need to feed.
Air is exhausted by a 8" can fan.
I plant one clone a week and cut one plant a week.
I have indicas and sativas both.
Temp doesn't get above 78-83

In flower it's 8 plants at a time in a circle setup. Buckets on the ground and no tiers. 1000w hps mounted vertical in a water cooled tube. I have a heat exchanger also that runs in the tent to keep the temps 80 deg avg. With vertical light they only get to a little over 3 ft maybe 4 once in awhile. The bottom 6 - 10 inches are trimmed for the leachers.
I flush the last week with water and GH flush.

I don't have money for co2, dehumidifier, ac, or more light.
I top the plants because they stretch a little.
They are in hydroton and 6" lid net.

I've only got 75 grams once and avg is 60 per plant lowest is 45.

What can I change up ?

sounds awesome can we see a pic or two

Yeah a few pics would be great.

Stick with a strain that you like in potency and yield and work with it.Find out how the strain acts in different situations what it likes and dont like and im sure you will reach your goal everytime.

it sounds like he has a mother and is just taking cuttings changing strains may disrupt the process to much to be worthwhile it may even throw off his harvest a week timetable.
. ask fddblk he will be able to help you.

I don't have a mother I take cuttings right before flower. It's a pain but I love having variety. Side note : I did my first seed , feminized SLH and it is a female, whew.
I'll find some pics it's hard to capture with my iPhone.
