Hey guys can I ask a quick question. I am starting my seedling in rockwool,

1. when do I know when to transplant them, some places I read when a root starts to show out of the bottom, and others when it grows 5 sets of leaves, which is most optimal?

2. and into what size pot should I transplant?
3. Lastly after its first transplant when do I know its ready for another, I made a mistake thinking when i saw a root come out the bottom and it did not even have many roots?
