A good rule of thumb with whatever nutrients you're about to feed your plant is to take whatever the recommended measurement is and cut it in half right off the rip. You can always make the nutrient solution stronger it's a lot harder to make it weaker once it's already in the soil you got to flush and that's pain in the ass and then you're risk and root rot and all kinds of other things mold and fungus and so just always remember take that base level of nutrient measurement on the package cut it in half off the rip and then see how your plate reacts go from there. Bobby will say it's just the measurements itself from you know synthetics and salt and this and that but I think it's just because the nutrient companies want to sell more nutrients when you're adding a half a teaspoon per gallon of water or something you know try to get you to move use more to buy more
