I am in a coco DTW system. Having problems with iron precipitating out. I say iron… as it is black but I haven’t tested if it is magnetic. Just occurred to me.
Regardless, black precipitate in my reservoir. Here’s the recipe I am following:
GH Armor Si 3ml/gal
Peters 3.4g/gal
Calcinit 2.3g/gal
Epsom 1.2g/gal
Greenway Cal-Mag powder reconstituted per directions 3ml/gal
I know the cal-mag and Si are not typical in a 3-2-1 setup but I won’t stop using Si because it makes a huge difference.
The cal-mag is added as my plants continue to require more calcium and I was reluctant to just use more calcinit. I am not super familiar with the whole 3-2-1 as I have just recently left my four year affair of liquids. I am super familiar with this cal-mag preparation.
So, thoughts on the black precipitate?
