No. Promix in a 5 gallon using a 1 part food and no supplement under a 1000 watt HPS with good genetics easily produces 1.3 pounds of hard bud. If you try to add too much stuff it makes the plant suffer. Which is why I say less is more. Once you're mixing 8 bottles of stuff together it's too much. Promix is very forgiving. If you're having issues simplify the recipe. We literally go 3 weeks veg. 2 week of flower on veg food. 4 weeks on bloom. 2 to 3 weeks on just water. And it's good. Spray maintenance pesticide and fungicide maybe once a week for the first month of 5 weeks.
