Silicon Deficiency In Marijuana Plants

A silicon deficiency is extremely rare, but it can prohibit the plants from producing sturdy leaves, roots, or stems. Fungal and bacterial diseases along with insect infestations are all more common during a silicon deficiency. Photosynthesis is limited and the eventual yield is also lessened. Silicon is not, however, mobile.

Silicon is important for creating a barrier between the plant and pests or diseases. It is also vital for creating sturdy stems and branches.

Some of the ways to rid yourself of a silicon deficiency include:

  • Diatomaceous earth
  • Silica planting medium
  • Silicate salts
  • Liquid Silicon

        • Dt.,

          It depends on the PH of the solution after mixing. Some nutrients contain a buffer that allows the solution to fall into the proper range. Other nutrients do not and you may have to PH down or in the case of FoxFarm; You would have to PH up in most cases. The only way to tell is to measure PH with a proper implement
