I'm using rain water that was collected over 24. does rain water have such high Calcium content ?

Shouldn't - do you add stir well after adding Pro-teKt? I recall it can cause problems if not mixed well before adding the Foliage Pro. Were the concentrates allowed to freeze? do you water immediately after mixing? art there little white eggshell looking flecks at the bottom of the container?

If none of these pertains, you might want to send an e-mail to Dyna-Gro...you may have a defective product.

I'm on rain water and mine doesn't do that. It stays clear even a couple days later. I mix it the same way as you, except with some water in my container first (ie. water, then protekt, give it a shake, then FP and more water). If you're putting the protekt directly in your container first, could it be reacting with the material of your container, because it's concentrated? Just a thought...

I added 10mL of ProTekt while the water is filling the container. then give the water a good swirl while waiting for it to fill. when it's at about 2 gallons I squirt in 10 mL FP from a syringe. then turn off the spout.

I probably will try to add the ProTekt first and mix even more vigorously and wait a little before adding the FP and see if it still gets cloudy. maybe I'm adding it too quickly

The way you're doing it should be fine. How about seeing if you get the same thing with 1/2 the fertiliser dose ie. 5ml of each?

since spring I had been doing 5mL of each and didn't have this issue. i noticed the plants were growing rapidly and leaves were yellowing and falling, which I suspect is due to nitrogen def, so I increased FP dose

Time to ask Dyna-Gro! Please let us know what they say

I concur with Robin98, your mixing protocol should not be a problem.

Have you tested your rain water pH? Too low of a pH can cause nutrient lockout that may give the appearance of lack of N. Acid rain, or if you live downwind of an industrial area of some sort could cause unusually acidic rain water?

I'd def shoot an e-mail to Dyna Gro.
