Thanks Mr. S! Given that info it looks like the ULH and Z will be transplanted this week! Once in the final pot I'm assuming that I will continue staying away from the stem when watering, and hold at 2g/gal or bump up?
With autos there's a couple of things to keep in mind, or at least I do when I transplant. Right now the roots are contained to the size of a solo cup. If you over saturate the medium in the final pot then you have a long waiting period before you can get them a higher dose of food.No need to stay away from the stem any more, but I wouldn't saturate the entire pot. When I upcan from a solo cup into a much bigger pot, I water up to an inch beyond the original root ball, and extend out from there with each watering as the roots grow into the new soil. Going into a 1 gallon would be different.
I would say you're okay at 2g/gallon for now but wait for MrS for confirmation.
The idea is to water approx. two times the diameter of the solo cup hole, and a little deeper from the base of the hole, with an increase in nutes. Do your upside down sandcastle and water inside first, very slowly with a small pipette or similar. You water the rest after the transplant.
Since you are currently at 2g you would now feed the area with 2.5g or 3g. If you water the area around the where the solo cup rootball is going then it has some nutrients right away. You'll soon be doing a full wet/dry cycle, but you want to see some growth again after the plant recovers.
Don't forget the mykos if you have it. If your pot is already wet then you'll know for next time.
