Keep a record of the amounts of nutrients and additives you add to each tank of nutrients you mix. You then have a good starting point for the next time!

If you are using CANNA RHIZOTONIC always add this to the feed water before you adjust the pH; CANNA RHIZOTONIC is a natural pH UP product.

When you dilute an acidic product, always add the acid to the water, never add water to the acid, if it splashes it will cause burns on your skin or in your eyes!

The products designed to adjust the pH are concentrated products. It is sometimes difficult to adjust the pH correctly in one go. To make life easier for yourself, dilute one part pH adjuster with ten parts water and use this to adjust the pH in your nutrient tank.

Measuring the nutrient reservoir works as follows: Take EC/ppm as the starting point, measure it and determine whether it should be higher or lower, based on the values shown in the instructions. Only then should you adjust the pH if necessary. Try to get the nutrient solution’s pH value correct at the first attempt.
