What is best for raised garden beds using potting soil and compost?

I installed a drip system last year but I didn't plan it right. So, on to round two.

Question 1: I am using potting soil and compost in raised beds.
Is that considered loamy soil?. Will that work with drippers? I feel like last year the water just went straight down and didn't disperse.

There are some plants where going straight down is fine - i think- (blueberries, squash) but some that have a larger area to cover (lettuce, carrots, asparagus). Does it make sense to use drippers on plants with single "stem" and sprayers on plants that cover a larger area? If I use sprayers, how many can I use on one line? Would bubblers be a better choice than sprayers?

Question 2: I might have to make several lines to get under the recommended GPH per line. I have to attach the hose to my system, if I then do several T's at the beginning to split into 4-5 main lines, is that okay?

Thank you!!!!!!!

You need to blend some actual topsoil into that mix, or the water won't spread horizontally as much as it otherwise could.

Unfortunately, most of the beds are already planted. If I can't mix topsoil in, what option do you think is best?

Thank you!
