calcium nodules

Hi everyone, First time posting but long time follower. First of all I’d like to be clear that I am having our pool builder take a look at the plaster as it is only 8 months old. But I figured I would get some of your thoughts as well. Let me know what you think. Thanks!

We re-plastered our Maryland pool in late 2019. Used a WetEdge Quartz product (link below). The pool was winterized shortly after the 'curing' period (~30-45 days after plastering). I brushed the pool and did my best to keep the water chemistry in line with WetEdge's 28 day startup guidelines...
