When to start investing in Facebook ads?

I’ve been watching “How to Entrepreneur.” Is investing in Facebook ads considered scaling? When is it appropriate to start investing in ads? At what monthly revenue or profit for example?

I would like to increase traffic to my website and tempted to start Facebook ads. However, my monthly income is only 2k and I haven’t started paying myself yet. Should I still focus on increasing organic traffic first? The issue for me is lack of time and energy to do everything in my business but I definitely do not want to “grow broke.”

When would it be appropriate?
