pH - bringing back to neutral from Alkaline:
If the pH of your soil is too alkaline then you may want to
bring it back to a natural 7. To correct this you need to make your soil
more acidic. Here is a list of ingredients that can each be used to return
your plants PH to 7.
-Cottonseed meal
-Lemon peels
-Ground coffee
-Some Fertilizers also are very acidic and can bring the pH down to 7.
When using this method always moderately apply the
substance and check the pH. Over time you will know what measures
to use. This is best left up to the grower as he/she will know how big
their pot is and how much should be added. Experiment a bit and learn
as you go along.
pH up / pH down:
These products are available in most grow shops. They
actually act as a pH agent for adjusting your soil pH. They only come
in two forms - pH up and pH down. More and more people are using
these chemicals to adjust their soil pH.
