What are these puprle spots?

Yellow leaves are from being pot bound but the purple spots popped on some plants I just transplanted a week or so ago. I thought it had something to do with pot size but I now think it had to do with air circulation. Any ideas?

Have you been feeding her?

Yes very lil verde along with a tea mix purchased from my local grow store I got from a friend. I think she said the tea is from last season tho
