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.

Make sure to add the correct amount of nutrients to your soil in order to prevent Silicon deficiency. Prevent future issues with balancing your nutrients by giving your plants my Bergman’s Plant Food, which you can find in the store alongside a super easy to follow feeding schedule.

    • 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
