Hey all...Ihave a question about Epsom Salt.

As I was strolling the aisles at WalMart I passed by the epsom salt. I remember hearing people mention adding it to their feeding schedule.

So I picked a bag up and was surprised to see they have instructions on the bag for feeding to different types of plants.

My question is...when to use it on Cannibus? How much? How often? And what are the pros/cons to using Epsom Salt?

Im curious as to why adding salt to your soil would be a good thing. Salt build-up is a concern with plants in soil. Im sure it must not encourage nute lockout or people wouldnt use it. But why isnt this type of salt harmful?

Anyway...Im sure one of you regular users of the product could enlighten me.
BTW...I did buy the bag...but would like a bit more info on it before I actually use it on my plants.

Much thanks....in advance.

Epsom salts is basically just Magnesium Sulphate and is used to add high concentrations of Magnesium to the soil, it can be used as a root feed or a foliar feed.

It's not meant for general use - only for preventative or remedial use for Mg lockouts or when the plant needs a boost of Magnesium. Canna uses surprisinlgy high quantities of Magnesium and it can easily get bound into the soil by high salinity or highly acidic soil.

People do use it for preventative purposes usually a one off feed of 1 heaped tablespoon per 2 gallons or a teaspoon per 2 litres of water usually at or around the 4-6 week vegetative growth mark and another at about 2nd-3rd week of flowering.

If you're using a known water quality ph and EC, good quality potting soil, correct EC feeding levels and decent sized containers you shouldn't get Mg problems.

The people who suffer from Mg problems are usually those either using high EC tap water (with lots of sodium carbonate) which locks Mg into the soil, very acidic potting soil or those using distilled water with no tap water mixed in which doesn't contain enough Mg for the plants use.

Epsom salts should be treated in exactly the same way as any plant nutrient and fed at the correct EC levels when combined with other nutrients - ie don't feed it at too high an EC level.

This is not organic!!!!!!!!!!

Reeferman, could you please define what you mean by "organic"? In other words, depending on the use and applicaton (not just weed growing) I have seen the term "organic" applied differently. Is there a standard agreed upon defintion or is this just your opinion?
