The bit I put in bold.
You say that Epson Salts in a growing medium (cannabis plants medium) is to be avoided. Now I am interested in why you say that, and what you base that on. I understand that Epson Salts are salts, d'oh
and when a person flushes you flush to remove salts. However Epson Salts does not fix to the coco and is in fact a cheleting agent and will help remove build up of salts if used, or at least that is my understanding of how it works in growing mediums. As Epson Salts are Ph neutral I do not see how adding to the medium is going to change the Ph in the medium.
Now if the medium has a Ph lock due to other factors, then adding Epson Salts will only provide some mag to the plant it will not resolve nor really help mattes beyond the short term where the deficiency is temporarily dealt with - the root cause of that deficiency is still present. Magnesium gets locked out when ph levels are 2.0 - 5.7 and Magnesium is absorbed best when the ph levels are 5.8 to 9.1.
So since Epson Salts is Ph neutral I am unsure as to how it will negatively impact a growing medium.
EC and Epson Salts - I guess this is the part I would like a bit more detail about. How Epson Salts causes EC lock out. I do understand that plants will not feed if the EC is higher than 2.2 according to the growing literature (all plants not just Weed). So if you add so much Epson Salts that you push the final EC over that mark you have lock out. But you really have to add heaps of Epson Salts to do that I have found while testing.
