Accurately Measure Nutrients and Use a Balanced Nutrient Profile to Grow Superior Cannabis

My last flowering run was the first time in 15 years that I di not accurately measured my nutrients. Now I understand why most hydroponically grown cannabis is the way it is. Two Reservoirs, four plants and neither solution was accurately measured. The product from both reservoirs meets my OPB criteria. Other People's Bud.

Low yield, extra stemmy, burns hot, didn't fade like I'm used to, terpene profile is completely off, one set of plants was extra leafy and the potency just isn't there. Very disappointed in myself for this run. Instead of orange/citrus, the bud smells more like pine trees and the effect is just flat.

How Do I Measure Accurately?

Up until this last run I've always used a 60cc syringe and liquid nutrients. Though I have not done it myself, using a scale to weigh powdered nutrients would be the same accuracy. I would guess a gram scale with .01 accuracy would be fine, possibly too accurate?

The use of the syringe allows me a fine enough measure that I've not been able to notice a difference in quality anything like this before. This last run I used a tablespoon measure and I'll not be doing that again.
Balanced Nutrient Profile?

Cannabis is an accumulator plant. When more nutrient is supplied to the plant than it needs the extra material is used for structural support. Like extra layers of paint, the extra is used up within new growth. On top of all this, the profile needs to be balanced to account for the pH swing as well. Without a full pH swing I don't believe it's possible to grow truly clean cannabis.

Cannabis evolved with a pH swing. In soil the pH swing is a mild one as the soil dries out. With roots-in hydroponics systems the pH swing must happen within the reservoir. Roots-out hydro systems go through a mild pH swing as the medium dries out between waterings. In each case the best cannabis will come from setups that provide a full and regular pH swing.

What Do I Use?

I use a base mix that works decent with nearly any cannabis strain and then tweak it to the needs of each specific strain I run. I use that mix in an environment that provides a full pH swing within the beneficial range. The tweaks I use are very minimal and, as I've so recently found out, need to be precisely measured.

I use very few additives and am careful to match their effects on pH to keep things in full swing and healthy. I use a bit of quality Epsom salt, some liquid silicon at proper times and an appropriate amount of fulvic/humic acids. Cannabis requires very little else than micro/macro nutrients to produce superbly complex and delicious terpene profiles.
