Hi Patricia, it is tough for me to give specific recommendations for MgSO4 rates without knowing more about soil type, pH, and the type of plants you are growing. If you are located in the US, I would suggest submitting a sample to your state's cooperative extension service (usually associated with your state's university system). They will be able run soil tests that are appropriate for your soil type and can also provide fertilizer recommendations based on the results of those tests and the type of plants you are growing.
Could you show plant under natural light?
How much magnesium sulfate I need to put to acidity soil?

You should not apply mg in soil. You should directly spray on plant leaves for better result. Dose 250g/14 liter water (magnesium sulfate)
