First super soil 1lb attempt

So I got a couple white rhino monster cropped clones about 7 weeks back. After reveging them in solo cups for a week I transplanted them into 5gal air pots. I'm using a super soil recipe i amended at home containing blood meal, bone meal, bat guano, dolomite, azomite, rock phosphate, humic and folic acids. After having them in the grow tent and in the 5 gal air pots for 6 weeks in veg they have had some explosive growth..

What I'm wondering is if the 5 gallon pot is going to be enough root for these girls to attain a 1lb dried harvest? They are looking great, healthy, and have dozens on dozens on cola shoots. But the height just isn't ideal and I'm not sure how long I should continue to veg these girls before switching them to 12/12.

I've attached pictures of the girls when they were in revert and a picture of them today after 6 weeks of veg

I just broke the 1lb mark using supersoil in a 30gal pot. I doubt 5gal would do. I usually get 4-6oz from 5gal buckets
