Something wrong with live rock??

The picture has too much blue for me to tell

Is this in a newer system? Probably diatoms, which is normal for a new tank or if you somehow had silicates or phosphate added.

Is this bad or what does this mean? My other rocks don't look like this just that one side

It can be normal in a new tank after a cycle how old is it and how high is your n03 and p04

Looks like a mix of diatoms brown, the bright green coraline, and red cyano. I wouldn't worry about it. Most rocks do that before they become encrusted with purple coraline. your tank is just starting to grow algae on rocks is all. I think its a good sign IMO.

Just watch your nitrates and phosphates. As long as they stay low you should be fine.
