next time transplant your clones a few pot sizes up before putting it into a 10 gallon pot.
you start in a solo, go to a 1 gal, then a 3 or 5 then the 10.
a solo cup of roots planted in the top bit of ten gallons of dirt needs a LOT of attention and care to get the roots going. you water your gallon of water, which is 1 tenth of the container, and it goes right through to the bottom. it does this because that root bundle is of a different density and compression rate with a crowding of roots in it, so the water goes right around it and to the bottom.
normally, when you take the solo to the 1 gal, it only has a bit of space for the roots to work their way to the water. so the plant gets a bit sad, but swaps its efforts to making roots get to water and veg growth slows and the plant wants to eat its reserves (starting at the bottom, leaves start to shrivel and crinkle and brown) with a solo to a 1 gal, this is not difficult, and doesnt take so long. so the plant doesnt eat itself much and goes right along.
poking something into the original root ball will let some water get to it, but you are in save it mode.
