So i just got my TDC pen and had some ph adjusted water that i put my TDC pen in and it reads 345 this seems really high for just water with no nutes? Is this number even relevant?

When i do start putting nutes in my chart says 200-300 ppm for week 1 does that mean that i am adding 200-300 more nutes in? so essentially 545-645?
