How get My ec up

I agree with UBU,

EC is just about concentration of nutes.. add more per gallon or liter etc.. if you like your ratio, add same % to each product.. 25% more or 50% more etc.. should equate to change in EC too. so if you want your EC 15% higher, add 15% to all your doses. EC is not "ppm" and the "ppm" that device shows is just a conversion from EC. It's possible that some EC's do not translate as well as other EC to actual ppm of the nutes, but usually pretty good. I calculate this stuff from guaranteed analysis labels to avoid this 'error' that is intrinsic with using EC or ppm from a TDS pen. but, as long as the reading is consistent you can use it the same way.. it just might not translate to someone else's garden 1:1. Kinda like using a lux meter. good infor to learn per garden but doesn't translate to other gardens 100% accurately - close but no cigar.
