What am I doing wrong? Or am I just being impatient ?

As above, give full parameters. I'd also stop adding anything to feed the corals, you're not at that point yet where you need to worry about it. The tank timing sounds fine, so I'd be looking at water quality. The fish can take a lot poorer quality than corals can. If you have a skimmer, then yes, you should get it going
