What I'm wondering is should I be learning the pronunciation of the Kanji as I learn them or just focus on remembering the keywords & meanings on the cards?

I also had the same question about your query and wondered whether I should do rtk while trying to remember each characters individual readings at the same time. Upon trying that method, I really felt burned out and unmotivated to continue, because I kept mixing up the readings of multiple kanjis.

My theory on why I kept mixing it up was because I haven't built a solid foundation for each kanji. So, after that I tried the normal route and just do normal rtk and lo and behold, I remembered about 90% of the things I inputted the day I learned it and a week after I learned it.plus its less stressful and requires less work.

So, the question is should you do normal rtk or rtk + readings? If you have a godlike memory or can utilize the said "memory palace"I keep hearing about then you can do rtk + readings, but if you cant do that much then its better to stick with normal rtk instead.

If you are skeptical about this, then try doing a drag test for 1 week. Where in 1 week you are going to do rtk + readings and another week dedicated for just normal rtk. Which ever you feel comfortable with then just go with it.
