True Living Organics - The Ultimate Guide to Growing All-Natural Marijuana Indoors (2012)

As you acquire TLO skills, having available magnesium in your soil mix from multiple sources will
be easy. At some point you may overdo it and have too much magnesium; I was a victim of this very
thing myself. The soil mix in your container gets like a crust on top and becomes very hard. The
effects of an overdose of magnesium on the soil structure makes it tough for water and air to flow and
penetrate the soil mix well, and in TLO that is very bad. Life needs plenty of air and about life, these
things need to be water, and as TLO growing is al provided in abundance!
REV’S TIP
Rev’s Tip: Controlling pH in TLO growing is rarely a concern.
Balancing and buffering your soil mix, along with using a pure water
source, makes all that pH stuff basically irrelevant. Liquid mineral supplements usually raise the
liquid pH, and things like 100% grape juice and lemon juice lower the liquid pH. Doing this can
have detrimental effects on the microbeasties, so I hardly ever concern myself with pH of liquids,
because I rarely use anything but water and organic teas, which I will tell you about later in this
book.
I have grown very successful TLO crops using CaMg+ by General Organics, with reverse osmosis
filtered water, and using about 10 drops per gallon (or until about 65 PPM on a TDS meter) every
time I watered or fed with a tea. Consider this sort of application if you are shy about using calcium
and/or magnesium. This particular product has a 5:1 (five to one) ratio of calcium to magnesium,
which in my opinion is awesome for cannabis growing. Choosing whether or not to use this kind of
product will depend a lot on the mineral value of your chosen TLO soil mix, but if you are using a
pure water source, you may benefit greatly from dialing in a certain level of this type product every,
or perhaps every other watering.
