Yellow Sludge/Slime Seperating From Calcium Nitrate? WTF?

So I've been using this brand Hi-Yield for a year plus at this point and just got a new bag of it.

When mixing it with water I get this weird as separation that looks like yellow sludge. When i touch it its slimy and sticky and the water remains cloudy.

I use JACKS 321 by the way.

Also has anyone used CalMag+ with Jacks 5-12-26?

That looks like precipitate.

What’s your method of mixing?

Just water & HI-Yield or a 3-2-1 solution & HI-Yield? What is the Hi-Yield supposed to do?
Just water and Calcium Nitrate. Hi Yield is the company.

I mix everything separately until dissolved. In there own cups. Then I add it to a full res. Add PH Down and and then check PH/PPM.

Hi-Yield Calcium Nitrate is what it is. I called Pete directly from jacks and he said its fine and basically the same thing. I've used well over 8 pounds of the year with no problems.

Now all the sudden I get this bag and this garbage come off.

I buffered my coco with CalMag & didn't add CalMag until my last fertigation after reading the CalMag direction again. They stated it should be used for the 1st 2 weeks of veg. I'm in wk 5 now so I'm pretty late but the plants are growing well overall.

I believe the proper order is silica, then CalMag, then other nutes, then microbes, enzymes, etc. My CalMag bottle makes it known to put CalMag in first.
If you want to get to technical the correct procedure should be.

pH down before silica to around 5.5pH

Add silica mix throughly.

then add everything else.

as most silica products increase pH it’s always best to pH down your water to allow for the increase in pH from the Silica addition.

That way you’re solution doesn’t hit above 8pH.

I don't PH the water at all until after.

I've been doing it this way for almost 2 years now with no issue. its only happened with this new bag. I didn't know if maybe someone else had this issue or knew what it was.

I don't use silica.

I fill my res with water.

In 3 sep glasses I measure out Jacks, Cal, Mag and use warm water in each to mix until disolved.

up until today with the new bag. Everything is mixed and disolved with no issue.

However today. with the new bag As soon as I start mixing the Cal, this happens.

One at a time starting with Jacks, Then Mag, then Cal. I make a whirl pool in the res and slowly pour one at a time each in the order mentioned.
Then I add my ph down.

Never had any precipitate out

I've been pH'ing at the end. The Botanicare product, Silica Blast, states "In hydrogardens apply to reservoir every 5-7 days and adjust pH to 6.0." That seems to counter all other advice I've read.

Next time I'm going to pH down first as you suggest and again at the end if necessary.

That is odd. I'd return it. Maybe it wasn't stored properly before you got it.

Did this happen when you dissolved the calnit into water, or when you added the dissolved calnit mix to the res? Also, what order do you add the dissolved nutrients to the res?

If you've been doing it the same way for 2 years and have used this brand of calnit before without this happening then I would suspect it's from the current bag. The way you're mixing is fine. It shouldn't have that yellow sludge when you dissolve it in water. Some calnit is coated. I wonder if somehow some of that got in the bag. Does it look the same as what you've been using in the past?

I used Mega Crop and had the same yellowish fallout. I've never had the problem with Jack's though. I think I may have been mixing the MC in the wrong order though. That's why I asked.
