Drought! Stunted! 1 Blade! F**ck me!!!

I planted these girls late in may b/c of elevation and late arrival of spring. I have a grow journal posted on this site are a couple pics pre transplant in may and also of what they look like now. Not only do they have 1 blade (A couple might finally be going back to 3/5 after last check) but they have only grown 6-12 in. since transplant

A) True they have filled out but shouldnt they have grown 2 ft or more?

B) I can only visit every 2 weeks, how can I water and know how much to give (ex. 1/2 gal per day per foot? ect) without overwatering?

C) I just bought some liquid shultz and used in the last pics, any suggestions on nutes for outdoors and to help me finish off?

D) When transplanting to the ground I only cut off the bottom of the gal jugs to promote deep roots. Can I cut the rest off the tops in the pics and add several inches of good garden soil to give them more room to root?

Thanks for the help everyone, this is my first post so any suggestions to make it more readable, or if I was vague about anything let me know I have plenty of pics. Its so frustrating to see months worth of work almost slipping through your fingers............

Some of these plants look to be revegging be patient. Feed them something high in nitrogen. You will be fine keepem green dirrtyd

Yep those single leaves are reveg! Just wait it out!

Thanks Im sure I messed up by leaving the girls under 24/0 so when I put them out they started to flower. Im more concerned with giving more room for the roots by cutting off the rest of the jug and adding several cu ft of black gold. Ive only got about 6-8 weeks left of veg and would like to see them at least 5 ft tall.

Check out my latest video in my grow. You will see that one of my Green Crack is doing the single leaf reveg as well.

Any outdoor farmers with some experience that can help with these other questions? I'd really like to know if I should add 4-6 in more black gold and remove the rest of the gal jugs. I know the roots like to spread out, but will promoting root growth with 4-8 weeks left of veg keep them from getting bigger? They just pulling out of flowering and revegging as it is, I dont want to slow them down any further. Thanks in advance
