  1. Hi everyone.ive been doing my fair share of reading and researching,on (and off) this site. I have a few particular questions that i cant seem to find answers for. First. Whats the deal with ppm's for botanicares nutrients? Ive read that i want to start out anywhere from the 250-400 range for seedlings. But the directions say to use 7.5 ml per gallon. Thats waaaaay over 400 ppm. I use 1/2 strength pbpg and full strength cal mag and liquid karma and im at about 660 ppm. Is that about right? It doesnt seem to burn the plants..ive also read somewhere that liqid k shouldnt be used in DWC systems, like me. Something about clogging the roots? Even went so far as to say (mostly) organic nutrients werent as good as synthetic ones in a setup like i have. Thanks for your help.. :)
