Your question is pretty wide spread. You probably just need to play more games.
Make sure you have the right setup (runes, masteries,starting items- can depend on jungle route).
Know all first clear routes and their advantages+disadvantages.
Watch the map, you don't need to watch red buff dying from your autohits.
At loading screen ask yourself: which is the easiest killable lane and in which lane should I NOT gank.
Always predict the enemies movement and where their jungler will show up. Do you want to countergank? pink ward? or do you want to avoid 2vs2 situations. Your midlaner goes back--> don't invade without information. Enemy jungler top side -> invade bot side.
Pick a top tier jungler! Especially if you have no runes or masteries this will make a really huge difference if you pick someone with a good first clear. There is a reason why some champions are top tier^^
Just a few but the most broken tip is probably this one:
Whenever you pick a jungler: Go to mobafire, search a guide, click on advanced, author: high elo
Diamond or higher is fine. (platinum is okay) Read through it and watch the videos. Once you have done it with 1-2, start speed reading them. You can even do that in champion select or at loading screen. This is probably the easiest way to figure out a lot of things quickly and find a lot of information.
counter the jgs camps by leaving the smaller ones seems to stop the spawn of red blue buff if im not mistaken. also watching replays from pros from lolskill.net via replay.gg works.
