Gelato is a cross of 2 different types of Girl Scout Cookie variants and is pretty easy to grow. It was one of the first cultivars I started with and I loved every minute of it.
I think many of them are ordered from CoffeeShopSeeds based on my research with many of the descriptions matching up from that website and they sell bulk.
Quality seems to be on par with Euro genetics like Seedsman or Barneys.
I recently put some beneficial predator mites on my garden called Cucumeris and they kinda look like that. I think its a dust mite or something not harmful.
My pistils will prematurely turn brown like that when I accidently bump one or if a leave is touching one etc.
I'd keep the plant and learn what you can from it
