can someone give me some advice on this stuff

i bought a few sample packs of ChaChing---beastie bloomz--and open sesame---never used anything like this --been reading but i need first hand info on what they each do and how to use this stuff and when.i am growing lr#2s --10 of them

I find foxfarm salts too harsh. their heavy metal content is crazy in the double digits and do no good. I have tried it back in the day for several applications and had shite results. I would recommend staying away from anything with npk numbers like ff salts. with that said if you paid for it and want/have to use it...use it sparingly like a 1/16 dose of the label recommendation . good luck on your grow!

the grow is about done--it says use as a finisher so i was wondering---heck it was 7 or 8 bucks for 3 tablespoons of each with free shipping so not a big waste
