blue lab guardian ppm reading?

Got a blue lab guardian last week This maybe be a dumb Q but why does my ppm reading go up as the days go by shouldnt it be going down?

Thanks

Your plants are drinking more water than nutes. Plus factor in evaporation.

Moonunit, Thanks for the reply any thing I can do to get them to take in more nutes? or any other tips for 1st timer with ebb? They are looking great so far and Im real happy with the rate they are growing. Thanks again

Room temps may be a little to high.

If not just put little less nutes in next time u change res!

I usually top off with a bit of plain ro water

Room temp is 75 and water temp 73 yeah i been adding 1-2 gal a day to keep the ppm down..I have another problem my leafs are getting curly its only happening to a few of them at first I thought it was just new growth not so sure now any thoughts?

Your ppm is too high. Plants are taking more water than nutrients. Add water and lessen your nutrient concentration on your next res change.
