I can tell you from experience that with the floranova series nutes, you will never need to use more than 2 tbsp of grow per gallon of water in veg mode and when transitioning to bloom you should do 1 tbsp of grow and 1 tbsp of bloom per gallon of water. Then after that week go straight to 2 tbsp of bloom per gallon of water. Never necessary to mix any stronger than that. Any stronger and you risk nute burn on your plants.
