Just did a slurry test

PH was around 6.3 but PPM was only 200-300? The PPM going in is roughly 600-800, I read this can be from nutrient lockout? IF so how do I correct this?

Promix BX soil
frontrow AG Part A and B (2.5 grams per gallon each.)
Tap water: 6.5PH 120PPM
Water after nutrients: 6.2-6.3PH, 600-800PPM
Slurry Water: 6.3PH 450-500PPM

Wouldn’t the ppms come out higher or unchanged with lockout? Because the plant is locked out of them? I dont have the answer im just curious

Not so sure, which is why I'm posting... I also checked runoff and it shows 1200PPM and 6.3-6.4PH so not sure which one to go by?
 
pour thru and slurry testing give widely different results. which did you do?
Never mind, saw you did slurry test, is usually lower PPM than input.

Nutrient problems can show up in your crop very quickly. Perform regular soil tests so that you can identify problems early and take corrective action. Train your staff to recognize nutritional disorders so that they can scout while working in the crop.

What ppm is your feed? 600ppm or 800ppm? That's a huge difference. Should be giving them a consistent feed. Why a slurry test do you have an issue or just testing because?
