^He got it. I was hoping it would be so clever and funny that it would catch on, here on the forum, and all your buddies would start addressing you by various forms of "Ricky Martin Man". haha.

Bro..I'm using ur mix I read from another thread. 1.6g/gal calnit, 1.1.g/gal epsom salt and 5g/gal maxibloom mixed in that order..no cloudy res and totally loving ur mix! I mix a res and it lasts for 5 days without a problem. Hand watering my coco garden. I live in a third world country where someone is importing maxibloom which is hard as a stone. Inevitably I use a hammer to break it all down and I end up ripping the packet and breaking the spoon provided...lol. God knows how old the stock is..I did some reading and I think I have figured out what's been happening with my maxi grow and bloom precipitation issues. GH's calimagic uses calcium carbonate and magnesium sulfate to supply calcium and magnesium. They use calcium carbonate because calcium nitrate is incompatible with maxi grow and bloom. I've been using calcium nitrate for the last 6 months and I used a gallon of botanicaire's cal-mag before that. Calcium nitrate is the calcium source in cal-mag. If I had used GH's calimagic no precipitation would have formed. It appears I have been precipitating calcium phosphate. Long story short if you're using a brand of fertilizer use only their products. @rkymtnman you sir were absolutely correct. Operator error. Son-bitch. I really screwed the pooch on that one.
Fertilizer Compatibility
When mixing fertilizers, it is important to check fertilizer compatibility before application. If incompatible fertilizers are mixed, they form insoluble precipitations that can clog drip emitters and damage sprayers used to apply foliar fertilizers (Figure 1.). This article discusses a few scenariovegcropshotline.org
Scenario 1. A grower is using 20-20-20, a complete fertilizer to fertigate tomatoes. To prevent blossom end rot, he decided to add calcium nitrate in his fertigation program. However, problems may be caused by the application of these two fertilizers. The reason is that calcium from calcium nitrate and phosphate from ammonium phosphate in the complete fertilizer may form calcium phosphate, which is insoluble in water.
Both ammonium and phosphate are present in maxi grow and bloom. Adding calcium nitrate precipitated calcium phosphate. Operator error at it's finest. However, I am very happy with my decision to move back to jack's. My plants have never looked greener or healthier and the cost savings is outstanding compared to maxi. I feel complete now that I've figured out what the issue has been. Calcium nitrate is not compatible with maxi grow or bloom.
I wanted to ask you do you change anything when flowering or do you use the same mix from start to finish?

Yes. You can use that formula start to finish. That's awesome to hear it's not going cloudy in your res. It seems to be a rarely reported issue. I'm wondering if maybe I just got a bad batch of maxi that caused those issues in my res. It's an effective fertilizer especially if sourcing alternatives is difficult in your home country. I'd give them 3-4 days of plain water at the end before you chop 'em down, but that's about it. That's funny you mention the hammer. I use a blender with hot water to break down my dry fertilizers and get them into solution nice and easy because getting stuff like maxi or even jack's to break down completely is a real bitch

Nice to know it can be used from start to finish. Is it normal that some white particulates appear after mixing it all in the bottom of the res? Nothing major but something here and there...Yes.

It's pretty standard when running maxi. Even though I used a blender to pulverize that stuff with hot water I could still see chalky tiny particulate floating around. Never hurt a thing. It shouldn't cause you any problems.
