1st things first. Relax and have a beer. Gluten free beer is going to always act different.
1. Did you use yeast nutrient? Gf wort ferments slower, up to 4 times as slow. You will very rarely see a krausen.
2. If your beer is pale the hops will turn it green. After fermentation they'll drop out of suspension and the beer will be yellow.
Ps it's good courtesy to put up your recipe so more experienced brewers can help. Not having a go at you, just trying to be helpful.
