432ppm is pretty high. Once you get the nutes in there and mix everything up you're looking around 700-900 ppm for a basic feed thats should be looking more like 300-400. Without knowing exactly whats in that water it could certainly cause problems down the road.

What is "That 70's Grow"? Are you hydro, coco, soil?

I assume you mean 432 ppm. That's a bit high for a base. If a good portion of those ppms are calcium and magnesium, you might get away with it.

Added to much Calmag on my first feeding Did my first feeding today- of course I fouled it up. I added 3 tsps of CalMag to the gallon of water - rather than the 1/2 a tsp I decided on. I mixed the Calmag with Grow Big and Big Bloom- how bad was this error? Thanks in advance for some feedback.

Runoff PPM Can't really find a solid simple answer to this question anywhere.. Should my runoff PPM be half of inflow, the same, or something in between? I imagine there's a different answer whether doing feed/feed or feed/water, I'd really appreciate it if someone could map this out a bit

Advanced nutrients in soil runoff Advanced nutrients in soil. Hey, so I'm using advice nutrients line (sensi) in biobizz soil (light and all mix 50/50.) Anyway my runoff is always 5.8PH I'm guessing this is due to the PH perfect technology. My soil is buffered to 6.2PH and I always PH up to 6.3/6.4...
