I ordered some chelated iron with other minerals for my grow I have used it in the past and I don't think it will hurt anyway has anyone used it with their feeding regimen? My new growth is kind of light my pH is great and I ruled out heat stress so after some research that's what I came up with
I think it will do nothing adding it. If your ph is correct there is no point in adding it. So to answer your question No It will not harm your plant .
i will be feeding tonight i am going to use it just to see what it does to my ph i am also going to use molasses cant hurt right? i have some banana peels cooking too
