About Essentials
Why Essentials
The plain, well-priced versions of the things every grower needs: acid and alkali to hold the solution in range, a drop-test kit that needs no batteries, a fulvic acid additive for uptake and a straightforward PK 13/14 for the mid-bloom week.
Using them
Add pH Down or Up a little at a time, stir, wait and re-test. Fulvic runs through the whole cycle; PK 13/14 for about a week in mid to late flower.
