If so, why does this happen and is it bad?

I looked at my coolant tank and it was below the min line. Is this normal?

the res tank will crack and you will lose fluid. just need to buy a new one and install it

the tank looks brand new and i dont think its cracked. Isnt that cut hose underneath a purge line?

pressure. Have you seen coolant loss from that hose, or are just simply losing coolant and don't know where it's leaking from?

This is normal, but it will only lose like 3-4 ounces a year this way. If you have only lost a slight amount, then I would consider it normal. Add a small amount of distilled water or 50/50 G12+ & distilled water. 4 ounces is 1/2 cup, BTW. If you have to add more than 8 ounces in a year or so, you likely have some sort of leak.

I lost a lot, from max to below min in a few weeks. Where are likely spots for leaks to occure?

some dried residue at the back of the engine from up top. IF you can't find any external residue then the next logical place to look is inside the engine, but this is extremely bad news. Find that leak ASAP!

Ok, thank you. I think I'll try replacing the cap first before the block, lol

That's an overflow line.
