I was just wondering what calibration you’re using and you’re using a blue lab truncheon
Regardless of what others are feeding doesn’t mean that’s what you can feed at.
environment plays a big role in nutrient absorption for plants.
if it’s too hot they’ll want more water and less nutes and vice Versa etc.
I’ve made my comment of you’re feeding too heavy.
but I guess you’re right and I’m wrong because others can feed that high.
good luck figuring out your problem when you clearly don’t have one because other people feed heavier.
