Blog topic ideas researched to boost organic Google traffic

Hi! I already have a very talented guy to write my blog post. I am just struggling to find enough engaging blog post ideas since we post a blog post bi-weekly. I am interested in finding low competition search phrases with as many search hits as possible that answer questions for our potential customers. I want to grab potential customers by answering their questions via blog to get them into our sales funnel. I am asking for someone to go to our website to see what we are all about. We have a blog section on the website so you can see what we have already blogged about. That way we are not getting repeats.

We own an all-natural bath product company. We focus on moisturizing bath products and we only use all-natural ingredients with 100% essential oils for our scents. Our primary focus is bath bombs and bath teas. Secondary would be what we call "salt soaks" which are our premium version of the typical Epsom salt bath. Blog post ideas could be about ingredients in our products (as seen on our website), solving health concerns, self-care, alleviating or soothing skin conditions, or anything else to engage a reader that would be a potential buyer.

I personally have used Google Adwords keyword planner but I am running out of ideas. So maybe you could give me a list of 100+ post ideas with low competition and relatively high traffic that are pertinent to our business?
