O ya....so I ran dyna gro, just know- the stuff is super concentrated, like really strong stuff but good stuff...You can feed 3- 5mls of the of say their veg per 5 gals of water and be good. I also found there bloom to strong, I used there veg in flower and would mix in the bloom later in flower. I forget the ratios but say like 2-4 mls of veg and 2 mls of bloom per 5 gal/water. I didn't have the setup I do now but still got good results. Their pro-tekt is hands down the best silca on the market, no one should buy any other silca as far as I'm concerned. I just like canna a lot more for my base and additives. I believe canna is great for all of you using tap water, my buddy grows with tap in soil and uses the canna terra line and kills it. Best thing about canna for him is ph is usually right on in the 6.2 to 6.5 range after mixing his nutes in. He told me if he adds another product but canna his ph goes way up or down. He started adding nftg zues juice and aprhodities ext. cause I was using it and he was like, my fucking ph is going down to 4.8 now, fuck!
