Macro nutrient mold - Problem Solved: Now preservation methods


Hey guys, macro nutrients aren't supposed to grow mold right?
If that's right, what is this?

My macro's will grow mold. When that happens I just pour them through cheese cloth, which removes most of the mold (whatever is left I can't see).

Not sure what macro's those are though. Mine are clear. Your macro's look like my micros.

Gotcha. I mix dry KNO3, KH2PO4, and K2SO4 to make liquid macro ferts. Never seen flourish before.

What did you mix? If it's the stuff I listed, it's all white powders and comes out clear. Plantex CSM+B is the color of your pic.

I got them from a seller on here premixed. I just added water. yeah that's why i'm thinking the guy that i got them from messed up labeling bc i have a bag of white powder too. I had the thought when I got them, but since the person is supposed to be well known, i trusted it

It's more common to get mold in the micros, and I'm guessing that's what you have in that bottle. Who knows though, maybe they are different macros. I have no idea.

Pic of my ferts for you:

yeah i should have totally trusted my gut i hope my big bottle at home doesn't have mold. I wasn't planning on opening the micro packages until i was done with my flourish comp (which i keep refrigerated to prevent mold)

do you think i could add the rest of my flourish to the micro mix bottle?

confirmed labeling error :|

also, good to know that you can still dose if there is mold present. it will not harm anything

Not meaning to hijack but I have read to add excel to one of the mixes. Can I add it to both or only micro or macro. I have both in refrigerator. Also is metricide ok instead of excel.

i use Ascorbic Acid and Potassium Sorbate to keep the solution fresh and mold/fungus free, you don't have to keep it in refrigerator either.

Is this a mix, or do you have more info on how much to use of each?

I don't dose excel or anything normally but I may look into it. I'm also curious about the other method- asorbic acid and potassium sorbate. how much? how do you get it, etc

I put Excel in my micro mix, about 5ml per 1L bottle and then keep it in a fridge. Strangely enough, I got a bunch of mold in my last mix, the first time ever. Go figure.

you need MOAR excel! I last saw 10ml to 500ml. The heck with that, I started doing what Tom does.. I use excel as my water!

Then again, you might not want to do that if you have shrimp or sensitive plants.
