Is my rate of nutrient PPM use OK?

I have a aero flo 60 running on a timer with level control tubes in runners all the way down and tubes are sloped. my last grow was with same strain direct clones I ran deeper in the tubes had nutrient constantly circulating my PPM were at 850-1500 Veg- flowering.This grow I see leaf curl down at anything over 800PPM Im running at 760PPM now and am 2 weeks into 12/12 I use 15 gal every 3 days when I top off it shows I used 200PPM with the 15 gal. last run the PPM didnt go down that fast.I have not tried to raise the PPM past 760 sence I switched to 12/12 Running the complete line of GH 3 part expert recirculating program .So the Question is would this be normal? and I like to go 2 weeks between Res. changes but it only holds 35 gal. Should I change out weekly, or top off and add nutes at the 350PPM mark? Thanx:mrgreen:

So no one has a opinion on this. Just looking for some advice to help me get my PPM right. I dont have PPM raising in the Res. they hold steady until I add back water to see the ppm used it is around 200PPM less than put in and 15 gal gone should I adjust my ppm until I see the ppm rise as the water goes down or is it optimized and it should be left alone?:wall:

I have lots of opioins lol. my ppm's start out around 220 I never go over 850 on my nutes. I don't know a thing about your nutes. Also I just top off with adjusted water when needed and change out about every two weeks.

yea i think you should change the water every week. I m at 1400 ppm last couple weeks of flowering. i started flowering some reallll small clones at like 800 and bumped it up like 100 every week. As long as they are doing okay, i kno they cud use more. Always make sure your parts are good. Leaf curling down could also mean over watering so lower the water level

Im in a aero unit with the pump on a timer 2sec. spray 6min wait between each spray cycle. I made the clones from the same mothers I used on the last grow. They are sour diesle
