Hello, First year growing potatoes. The ones in my raised bed look...strange? They've got white spots on them (almost like mold). They seem to have grown with "cracks" in a few. I planted ones in grow bags this year too and they are doing great. Look just like regular store-bought potatoes. Same variety. Same soil (new this year as new raised bed). I'd love to know what's going on so I can avoid it next year and I'd also like to know how to determine if my raised bed spuds are safe to eat. I've included photos of two of the potatoes. One washed off and one straight from the dirt plus a close up of both. Thanks so much!
