  1. i use bat guano thats high in nitrogen and high in phosphorus nitrogen in veg and phos in flower but my question is can u use to much i only use 3 tablespoons a gallon of water and use every other watering any advice
  2. You can over fertilize. I personally stick to every 3 days. But it can work every 2.
