The green is typical nuisance algae, scrape the glass and/or find something that will eat it for you. The red, though I can't see for sure is likely cyano (best syphoned out by hand until it doesn't reappear)


Likely causes;
newly established tank (if so, this is just gonna happen)
increased lighting,
die off from the new LR you added (have you tested the water parameters?),
phosphates/silicates in your make up water (tap, RO/DO ?)

Lots of variables to play with here.

BTW is that a chocolate chip star in the back? Mmmmm coral munchers.
