Nutrient Lockout – Lesson 24

Nutrient Lockout – Lesson 24


You’re mixing a nutrient solution and you
add your pH adjuster and you notice a milky-white swirl appear in your reservoir. What’s going
on? Sometimes when we pour a concentrated pH adjuster
into our nutrient solution, as it goes into the water and is moving around in its concentrated
form, it actually starts to bind with some nutrients in your solution into forms that
are no longer available for nutrient uptake by your plant. This is what people refer to
as nutrient lockout. Essentially the nutrient is binding up into forms that are no longer
available. How can you deal with this? If you know how
much pH adjuster you need to add to a given reservoir, you could add it before you add
your nutrients, so your pH adjuster is diluted fully without to throw your nutrient solution
and therefore no longer available in concentrated forms to bind up with anything. Another way
to go about it if you want to add it after you’ve added your nutrients is to dilute
the pH adjuster heavily before you add it to your reservoir. There’s definitely ways to deal with this.
It’s not a huge deal but keep in mind you want to provide your plants with the most
optimum nutrient solution possible, which means you don’t want to see any locking
out whatsoever.
