Lavender wedding cake

Well I had to lower ppm for a few days because right after I started after Rez change last week ph was rising but ppm where rising as well. Lowered ppm down to 630 ppm for a three days. And have been slowly bumping it up to 850 ppm. Goal this week is to hit atleast 900 if not 950 ppm. Going to put another net up hoping for this week seen how busy I get.
