For some reason, it seems like my plants do not uptake very much NO3 on a daily basis. The EI dosage I use is below. After a WC and reset, I test the NO3 (Salifert NO3 Kit) at 25 ppm and it only reduces by 1-2 ppm daily. My question is; should I dose fewer times per week? I'm concerned that if I dose as below 4X per week, I'll end up with NO3 at 100+ ppm by week's end. I think I understood Tom to say the approach is to to use for slow uptake is to dose the recommended dosage, just less frequently to address slow uptake.
Thanks for the help!
