Seedy poop? Formula fed

🍍

Hi all, today I noticed my daughter’s poop had a seedy texture to it. I know that that’s normal for breastfed babies in the early days, but she is formula fed (enfamil gentlease). She’s 10.5 weeks old and it doesn’t normally look like that, actually I think this is the only time. Is it okay if it’s a one off and happens from time to time? Or is it a sign of an allergy/intolerance?
