NP. Hopefully the 18-24-16 will help your plants. After you've given them a dose of high-P ferts to fix the deficiency, a good ratio for veg is about 3-2-2. Just multiply this by the size of the plant, so little plants would get 3-2-2 and big plants get the same ratio, just stronger concentration at 6-4-4, 9-6-6 and so on.
Good Luck
