Ok, so about 7 or so weeks ago I found a Canadian vendor selling the "new PH perfect" sensi bloom so I bought it. At first I was using the other sensi bloom that wasn't PH perfect. When I started using the what I call "PH stable" because it still isn't perfect, I saw really nice results, with a lot less hassle for me. After 4 weeks I saw some deficiencies. I had no idea whether it was Mg, Ca, Fe or my RO water screwing up. After getting an email back from high times, apparently the PH perfect advanced nutrients products COMPLETELY left out Iron... not only in the base bloom nutes, but NONE of their recommended supplements do either, as I use them too. If there's anybody else out there that has used this new formula... have you seen this same Fe def.? Its really bugging me out, because I was told if I use a cal+mag with iron, it could create toxicity from too much mg in my program. If anybody has any suggestions (besides the maxi-crop w/iron because its got chlorine in it and I use a bio active hydro system) please help me.
