Thanks very much for comments guys. Anyway, can anyone point more exactly what is so wrong with my spreadsheet? As I'm getting around half the actual delta-v that I should as result. I might have to do some mass adjusts, nevertheless, there must be something else wrong besides it.

Hello guys, I don't like to calculate Delta-V using ISP. I prefer to use the good old Newtons Law F = M x A. The problem is something is wrong with the spreadsheet I made. I'm posting a picture below, so you guys can analyze it and gime some feedback. Thanks very much.
