Is it okay if i deplete all of the planets at an early stage of the game? I've only recruited 2 members so far, and one of them was a DLC character. Now i want to deplete all of the planets in every system that are available to me. I don't really find it that boring, but that has to be because of the patch that fixed mining. Basically, is it okay if i depleted all the planets this far in the game? 
Also, about the N7 missions. I've only encountered 2 so far, and i was wondering if that's because i would unlock more as i progress through the main story. If that were true, then as i do main story missions, i would have to go back to the planets that i depleted, and check if there's an anomaly. Does it work that way, or can i discover all of them if i were to just scan all the planets right now? 
 
Hopefully you understand what i'm asking. Thanks!

If you find an anomaly and dont land (IE do the mission) you can return at a later point to do the mission.
 
I must ask: Why would you want to deplete all planets?

I don't really know, but i don't want to rush the game. 
 
Can i find all the anomalies early on in the game though, or do some of them become unlocked as i progress with main story?

You will end up wasting some money you could possible need later. There are plenty of minerals - more than you'll ever need. Money - not so much.

Alright, thanks for the replies.

You can do what ever you want, beauty of an RPG. Can I just say though, you crazy!

There is only one very specific point late game where doing extra stuff effects something, but you'll know it when you see it. Do what you wish, without consequence! Except...money is more important than minerals in the long run.

I think I waited to do the N7 stuff until after I'd finished the main quest. You'll have hit the level cap by the end of the main quest anyhow, so there's no need to worry about the N7 stuff in its totality right now.  
 
Plus, if I remember right, some of that N7 junk is a real bitch to complete. There's one where you fight, like, three Heavy Mechs at once or something. I mean, a real bitch.
