I am 17 years old, is it possible to know if I will grow up again?

bjr I want to know if I can still grow, I am 17 years old and I am 1m73 and I have gained only 1-1.5cm in 1 year but with a rotten nutrition, no sport nothing at all but since 2 weeks I've been doing stretching spine, leg, calf, etc. I started to drink more than 2L of water a day (I used to drink very rarely before, when I urinated it was all yellow this time it's all white), I'm starting to eat at least 2 fruits a day, and to eat healthy. I know that you can grow up to 21 years old and I would like to know if at 17 years old I can have a "2nd growth spurt"? what else can I do to grow up quickly please suggest some tips, I really want answers to my questions please. thank you in advance and is the "2nd growth spurt" possible by improving everything I said?
