If your just starting out, I'd stick with a general purpose all around fertilizer. Something like 10-10-10 or 20-20-20. If you have a green thumb, you can try bumping up the N&K by using something like 5-1-1 or 5-1-5 during veg and 2-8-4 during flower. Just remember the numbers themselves don't matter, it's the overall ratio of the NPK your looking at.
Your 10-15-10 is closer to a bloom fert then a veg, but it has enough of everything that you could get buy using it during both phases.
