What is the maximum PPM value I can go to when using GOLD NUTRIENT?
When using GOLD NUTRIENT do not exceed 1900ppm (total PPM including water) at any time. If your water is causing your PPM to exceed this level then you either need to purchase a reverse osmosis machine (which in most cases will cost less than $400) or reduce the amount of GOLD NUTRIENT you use until you come under 1900 PPM. If you exceed 1900 PPM you run the risk of inducing water stress on your plants which can result in stunting or burning.
