Getting better

im stuck around 1700 as of now and need tips and tricks to push out of here

I know multiple openings and have studied some endgame stuff already. Any suggestions?

Play longer time controls, in blitz u can hardly think about a position.

Rapid. Better Classical.
Find openings which suit your style best.

Excercise tactics sorted by topics like double attack, X-ray, interception, pin, ...
Use openings which allow you to avoid blunders.
Excercise pawn endgame.

Indeed rapid and classical only to get better, no blitz or bullet.
Play slower. Haste makes waste.
Let us look at an example
Your move b5 just loses a pawn and also loses the bishop's pair.
