Temperature/aeration/size/placement of your res...all can have a big influence on your ppm's. More info is needed...JAS

How long ago did you change/add nutes to your res?

Tables provide more surface area to lights, leading to more evaporation of the water, not the nutes, so ppms go up as water evaporates

Keep fresh pHed water handy and replenish daily, if needed. My system consumes ~ 1/2g per day

be careful when you get over 2000 ppm your plant will start taking a death dive.
