MANY schools of thought on that question...
i belive the chem 91 was renamed just desiel (pissed off chem) and then,, WEASEL?? crossed it to a skunk / hawaiiain ?? an got the SOUR d
But i dont care i love the cut of sour d i got some asshole joe gave it to me in northern cali . but thats another story
EDIT!!
that plant your posting about will be fine if you keep the soil slightly moist . with 1300ppm the dry ass soil is filled with leachate so barring any BUGS . that shit will be fine .
not on the subject but a HOT soil mix and plain water works better
IMHO
reedit just saw you got good advice from another member saying the same thing oops redundant
