there's nothing wrong with starting strength, but it's fairly limited. It's called starting strength because it's for "starting strength".
the lifts in SS are probably the ones that require good form over most others, so you are already doing better than most gym goers, so well done in that sense.
Blood and guts is very low volume, so you really have to get the most out of each and every exercise (as Darkoz mentioned, beginners tend to get more from a high volume routine)
weight lifting is not like flying a jet, you are not going to kill 500 people because you don't have lifting experience. If you use good form and the correct weight, you'll be fine.
Maybe you should do SS mon/wed, and hypertrophy stuff on the other bodyparts tues/thurs.
at least your getting something from both baskets. variety is key, and you don't "need" to do anything , everyone has opinions, you'll find your path.
