Transplanting from Aero cloner to coco issues??

Ok I need some help. I keep getting 90% roots, and then losing 90% of those on transplant. Aero water is pH Balanced NO nutes, Transplant Water is pH balanced and has some 0 -1 -1 bioroot root buster (fertilizer) at 500ppm (total with a starting of 300). Maybe I need more roots, maybe I need to water more than twice a day. Ideas? How much root mass do I need? Do I need some nutes in cloner after a point to grow more roots then transplant?
Help please.
Thanks

Once they have roots you can start feeding a complete nutrient right away at .8 ec. Are the roots dying after being transplanted to the coco-rotting? Do you have any pics?

You don't need much roots to transplant from clone into coco. Do not use nutrients in a water cloner, change water only.

In coco you want to transplant them in, fully saturate the coco and wait until they are almost dry and fully saturate again until a little drips out the bottom. Water slow.

As for nutrients in the coco I start feeding them with my normal veg recipe day 1 once they have roots and haven't had burn but with some fertilizers you will need to dilute it or risk burning plants at higher EC.

If you are watering them twice a day before they have established in the pots or drying out then that is too much.
