try adding magnesium instead,most think cal mag is the cure,might be,but magnesium and calcium work together just like bacteria and fungus,both have there place,when i hear
cal-mag my first thought is always calcium for some reason,i dont have any so cant say at what volume each have,the magnese control most of the otheres as in iron sulfur boron and so on i kinda see it as the agent that make all work,calcium is loaded in your mediums even your bro,the stuff you use it might not be listed but it there has to be,so like i say when i hear
calmag thats what i think is dominant in the mix from just the 3 letters upfront on the label,calcium can be many things,egg shells ,oyster shells and tons of others,guanos i think N,but some are more dominant to the P if you dig,all those macro nutrients are more important than most think,actually they dont think of them at all,until problems come up,most labeled nutes are pushing the N,P or K,nothing about all the others that make it all work,same as the health nuts,all want huge bulging muscles,protien ,protien well what about probotic's,there just as important but those product arent mentioned,my crazy ass look at plants the same as we humans,we are the same we both have to have soil to live and die in,if you dig,when the last time someone asked you whats your ph hahahah,i have been asked that and wut wut came to mind,we dont think about it,when my old ass wakes at night from cramps i eat potassium pills,when i cramp out in the sun i drink electrolites which is salt,salt is minerals dig what im saying,hell i dont know but this i do,it is a mind twisting deal and in know way is it a myth ,every thing happens for a reason ,my def of myth is something some believe and others dont,bodies minds all are difrent but no such thing as a myth,if you state its a lie ok im good with that ,but a myth isnt any answer at all,all you do in water is be the chemist you know how from sweat off your brow,you mix and grow thunder,i do the chemistry in the soil not on top but under,all the amends i told you i put in garden this year all 8 to 12 in deep,when the roots get to that depth they are only avaliable at only about 12%,next year this time they will be all availble ,takes time,the stuff you use and i use are the same all are minerals hahaahhha you have figured one important factor out,no matter what folk say about epsom salt,it is the asprin for plants,look at bag and you will see sulfur in it to, better stuff which is same just more for are use on plants is soluble magnesium sulfate, horticulture epsom salt all it is,magnesium 9.8% as[mg],sulfur as [s03] 32.4% sulfur as[ s] 13%,same stuff you use in hydro same as i use in soil,application is the key
