How to water pure and with nutrients

It's not required to feed it every time and might be counteracting what your doing with "feeding". Once a week is more then enough for Cannabis. When we are "feeding" it's not like we eat.. It's more like the plants just drink. And they drink their food. Having Ph in a proper range allows for the plant to absorb the food because the plants rely on water for photosynthesis and transpiration. The water is just as important as the feed if not more important. Water them ladies.. Use less... Grow more.. Your plants will be happier your wallet will be happier. You will be happier because you aren't overfeeding your precious plants :). From wikipedia. "Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.... Transpiration also cools plants, changes osmotic pressure of cells, and enables mass flow of mineral nutrients and water from roots to shoots. Two major factors influence the rate of water flow from the soil to the roots: the hydraulic conductivity of the soil and the magnitude of the pressure gradient through the soil. Both of these factors influence the rate of bulk flow of water moving from the roots to the stomatal pores in the leaves via the xylem.

Hard to say with no image or info. Sounds like you're not watering enough in 1 go. 20 ltr pot and 3.5 ltr? Should be taking 5 ltrs at least, get a small amount of runoff then it'd be good for 3-4 days. Sounds like a poor water/feed regime. I'm using canna bio and the soil and I go days between water/feed. Hard to advise a feed schedule on a plant I can't see...So I won't. Good luck 😉

It will be bad for my plant to feed it every time ?
