There are a few other points I want to touch on that are more important than the nutrient solution itself. Because if you do not have these conditions at their optimum state, the nutrients you are using will not be used to their maximum potential.
First, I want to touch on the temperature aspect. With CO2 enriched air at 2000 ppm's or higher, it is perfectly acceptable to run your temperatures between 78 - 82 degrees. Anything higher than that transpiration comes to a halt, and your plants will literally drown, as well as having internal damage from extreme heat exposure. Even with lower amounts of CO2 enrichment (1000 ppm - 1600 ppm), you should run no lower than 72 and no higher than 79 degrees.
Second, humidity plays a huge role in plant transpiration as well as disease/pathogen proliferation. Keep humidity at all times no higher than 55% during the flowering period to ensure optimal plant transpiration and non proliferation of plant and canopy diseases and pathogens.
Third, keep your water temperature at no lower than 63 and no higher than 72! Dissolved oxygen is most present in solution at 62 degrees Fahrenheit and is completely diminished at 80 degrees Fahrenheit. To reach optimum nutrient uptake, keep your reservoir temperatures between 67 - 70 for best results.
Fourth, as stated above, keep your CO2 enrichment at (or preferably above) 1600 ppms at all times during flowering. The more CO2 you pump to them the more they can use it to build sugars and optimize photosynthesis and bud formation.
Keep in mind everyone that the most basic elements for photosynthesis are Light, CO2, Water, and the Atmosphere conditions stated above. They all have a symbiotic relationship with each other. If one of these conditions is at 50%, they're all at 50%.
I cannot stress enough that the atmosphere is the most important factor in any grow!!! More important than any nutrient you can give them, because if these requirements are not fulfilled your nutrients will not be working at their optimum potential! Money is lost, and as expensive as these nutrients are, there is no need or room to waste.
Hope this helps! I know it sure helped me when I first learned it!
