I usually don't use additives but wanted to give it ago for one grow to see if it was worth it ay usually only use pk boost but see even now thats not worth it from what I've read I've got a few days left on my pk and need to buy other additives so I might just stop with them and just finish the pk and use the pk and A/B at the same strength
many growers use and like additives with excellent results. But they should be extra to enhance ratios and or microbe life. A fraction of the base nutes. NPK is considered the main elements (calcium and now silica are also) and robbing the plant of needed nitrogen and leaning toward high P products will always eventually antagonize or lock out other elements.
i do like to have higher K than N. Like in pure blend pro grow or megacrop.
