That would be good for ferts. On water changes I would do 30% once a week unless your tank is over stocked.

I dose a different route, I use dry ferts, but I also have 26 tanks so its cheaper for me to go this route. I also EI dose which is dosing everyday and doing 50% water changes each week.

If you can post picks of your plants we might be able to give you the names of the plants you have.
