Not exactly.. Bad proportions of chemical ferts may kill them, but then again, so will bad proportions of organics because they do infact break down to the same compounds as chemical ferts are made of..
Organics also provide a plethora of compounds beyond the typical NPK salts though, and microbial life tends to require these.. They don't need to come from organic ferts though.. Well they do I guess, but healthy soil is more organic than some ppl realize.. You don't necessarily need to add more organic products though, and proper addition of salts won't hurt them if they are types that are indeed symbiotic with cannabis..
