Yes. Foliar spraying is the fastest way to get nutrients to your plants. Be careful not to foliar spray flowering plants past their 3rd or 4th week. I’ve seen up to 20% increases in growth and flower production due to a regular foliar feeding regiment. Be careful with new products. I recommend only using a 50% ratio of the stated dosage, until you feel comfortable with increasing the use of the product. Also know that if you have a burn issue due to foliar feeding, it can take up to 3 days to see the results of burn.
