Aeroponic grow, new to aeroponics.

Flushed my system
Using full line Fox Farm Nutes according to schedule at 1/2 -1/4 strength

After all cal-mag, big bloom, cha ching, grow big (small amount, VERY), Kangaroots, Microbrew all added at 1/4-1/2 str my PPM was 550 or so. This was 3 days ago and now my PPM is down to 138, I stirred the res and still PPM 138. After I had checked my PPM after replenishing my res I PH'd the water to 5.8, did my PH up/Down products nuke the nutes in my water? Should I add more nutes?

Your plants used up the nutes.

As a plant feeds,the EC of tge nutrient solution drops as the pH rises,allowing the roots to take up all the macro and micro nutes.

In hydroponics, keeping an eye in EC and pH at least once a day and at the same time if day is a must.
