Also, with watering, grab yourself a moisture meter from Amazon or somewhere. Trust me they work absolutely brilliantly within coco. You just poke em in the pot and leave it in there. As long as you're in the green zone you're schweet. It's hard to describe where the boundaries lay so how wet or dry is too much. These meters will show you exactly where those boundaries lay and you will pick up a feel for where things should be. After a while it will become second nature and the meter will become less relevant but I still use mine just because its super handy to just glacé at a dial and see where I'm at.
Here's mine. It's a few years old now so the switch has gone a bit rusty lol
