having a little spider mites problem

How can I stop spider mites from distorying my veg plants. Can I use neem oil and luild soap and spray under the leaves or is it safe to spray the whole plant. What is a good neem oil? Dyna gro. Plan to spray once a week? How to mix neem oil and dish soap?

I've used plant vitality a few times and it has always cured spider mites, i bought the small bottle and mixed up half of it with water as per description. Still got the same spray bottle with the solution 3 grows on. good thing is you can spray everything plant and soil/medium. Highly recommend

What is vitality? What bran is it ? Is it neem oil and where can I buy this at?
