I'm doing something similar but with new domains, and I keep testing

In the first test, after post 200 in the first 2 weeks, all titles from the posts got removed from Google after reaching in 2 weeks to 5000+ impressions and 30 clicks per day on a brand new domain and 0 links, but the weird part is the blog still getting 30/40 impressions per day after the drop, and today he got 70 impressions... It keeps growing... i think my mistake was too much content too fast ... I am planning to start like 10 projects, and each of them has a different idea and niche

3 already been released, but all are new projects
