The AN 3 part is much cleaner than sensi for something like DWC. I used it for years before it was ph perfect, with hygrozyme and SM90 and never had any issues. The only other thing I added was the powder version of big bud.
I just read this post, I am doing this Krackty method on 1 of my plants this grow, so far so good, it is smaller than the ones with air-stones but she looks healthy as shiite. My friend had never heard of this and called me out on it saying I have to have an air-stone, nope you don't.
I have a tds meter that only reads ppm and it reads 500ppm and my ec meter reads both ppm and ec but I don't use it for the ppm reading because I don't quite get it. But maybe you're on to something. Maybe the tds reader I'm using is junk. I'm not seeing any major signs of nutrient burn so I'm not sure. I'll definitely be lowering my ppm and ec. See the pics below. These readings are all from the same bucket and thanks for the info!
I've been reading up on the different mineral salts and jacks has definitely been mentioned positively by the salt guys. I think I'm gonna try the jacks on my next one. I believe they said to add calnit. Also i believe they said to use mpk during bloom. The whole mineral salt thing is very interesting. Have you looked into any of it at all yet? (Other than the jacks)
i'm still on the fence about silica. i've tried it off and on for years and i'm not sure what if anything it does. somebody posted that a tissue analysis does show it being absorbed by the plant.
