This is after 4 weeks in primary. It is a Citra IPA and if it is contaminated I don’t want to waste my hops and dry hop it only to find it is sour. This is my 5th brew and I have never had any troubles, this is the first time I have seen anything like this.
Looks fine to me. Is this the first really hoppy beer you’ve made? That looks like bits of hops floating.
It’s going to be basically impossible for anyone to tell just from a picture. Certainly it doesn’t scream contamination. If you’re on the fence you can wait a few more days to dry hop and see if anything comes of it.
And incidentally, IPAs are best consumed fresh and a month is a long time to wait to dry hop. I’m usually in more of the 7-10 day range.
Take a sample and taste it.
I concur with the others. It looks normal to me.
That green gook is just hop matter & yeast.
Take a small sample to taste to be sure, but nothing about its appearance seems off to me.
HTH-
4 weeks is a long time for an ale. I’d taste it, if it tastes OK then I would dry hop it (using a bag) in a keg, burst carbonate and get to enjoying it.
