The leaves on my philodendron and phothos are turning yellow

Question

Could it be the water… Because there’s fluoride in it. I would like to treat my plant with something that’s organic or natural, no type of harsh chemicals because I do have small dogs. I have had this planned for 10 years and its leaves usually grow big and beautiful, now the leaves are turning yellow for some reason and I am not sure why and I don’t want to have to throw out my plant that I’ve had for so long. Can you please help me?
