If mixing fresh nutrient solution, do NOT adjust pH. Always Use Dechlorinated water. If nutrient solution is in a recirculating system, or stored over a period of days, monitor and adjust pH as needed. Do NOT over-use pH adjusters, as they will kill the active biology in Microbe Brew and Voodoo Juice. For hydroponics, make sure the water temperature stays below 72 degrees. Keep a submersible pump running in the reservoir to constantly stir nutrient solution. This step will aerate the water much more effectively than an air stone, and keep nutrients properly mixed. Some plants require more food than others. You may need to adjust the Grow A&B rates slightly, to make the perfect mix for your plants.
For increased stem strength and stress resistance, add Rhino Skin or Silica Blast. Foliar spray twice weekly with Piranha, Thalassa Tonic and Carbo Load.
