Not sure you need to water every day. Are you sure Sunshine mix in a 3 gallon pot will dry out overnight?

I suggest nutrients one time, and ph'd water in between nutrient feedings. I would monitor wetness of medium before watering every day.

It might be a good idea to mix solution according to bottle directions. Then check ppm to see if it is a good strength for you. Most times merely following the directions on the bottles works fine.

ph at 5.8-6.0
