How important are microelement quantities in hydroponics? I've found recepie for a blend for peppers on Kang stars yt channel, and since I'm planning to experiment with aeroponics now my foggers came, I'm trying to figure out if I can use some stuff I have at home.
He basically mixes 3g masterblend, 3g calcium nitrate 15.5-0-0 and 2g Epsom salt in a gallon of water.
I have "kristalon yellow" at home and no way of getting masterblend in my country. Problem is that kristalon has much smaller percentages of some microelements (pic related). Even if I adjust everything to get close to his recepie regarding npk quantities, I'm never gonna get micros as he has.. (I do realize I'm lacking Ca and Mg that he gets from calcium nitrate and Epsom salt, I'll deal with that later)
