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

container cannabis, and small skills like this make giant differences.
Overwatering does bad things and it encourages anaerobic microlife to come on to the scene. It
also tends to remove a decent amount of nitrogen from your containers; as the microlife start to drown
they grab air from the plant roots and from the nitrogen. This converts the nitrogen into a gas, and it
very literally floats away.
Salt related Issues
Too much of the “bad” salts can really make your TLO learning experience a living hell. Salt
problems usually kill plants, but not quickly, rather slowly and ugly. We will go through all the
directions I know of that this can come at you from, but always be switched on to this, because sea
salt and sodium are both OMRI rated, but are not really good for container plants in any real amounts.
All salt-related issues look fairly similar and affect the tips and edges of the leaves. The first and
most common place this comes from is your water source, and if you have any real amounts of
dissolved minerals (salts) in your water—like in city tap, or well/spring water—this can build up in
the root zone of your container plants. This will have at least two bad results that I know of: first the
salts will tend to dehydrate the root zone for water when the container dries out a bit, and second,
those built-up salts will change the pH locally in the root zone, effectively locking out absorption of
micronutrients. Of course the best way to avoid this issue is to use pure water, like reverse osmosis
filtered, rain, or distilled water. The other way is a counter-measure: you must flush the hell out of
your containers about every other week to leach those built-up salts out of the containers.
