I recently stopped using maxi and switched to Jack's 5-12-26 due to continuous unresolved calcium precipitation issues that contaminated my reservoirs endlessly. I tried everything to prevent the problem. RO water. Tap water. Hot. Cold. Don't add PH up until the day of water in. Omit the Armor SI. Mix PH up with a gallon of RO water and slowly add to the reservoir. Rub my tummy and tap my head at the same time while I pray for no precipitation. Nothing worked. Add maxi ONLY to the reservoir and not a single problem. I actually began using a strategy where I would mix my big 32 gallon reservoir full of maxi to hold knowing the maxi would cause me no issues. Then on the water-in days I would pull out however many gallons I needed, and then add my calimagic followed by PH adjustment. I know GH recommends adding the calimagic prior to maxi, but that caused precipitation so the order of adding did not matter. Adding the maxi first at least allowed me to keep a holding res full of fertilizer. In a nutshell the issue seemed to be isolated to the addition of calimagic. No calimagic. No precipitation.
So what's your fucking point jonny? I'm glad you asked. I had to go to the grow shop for some potting soil last weekend. While I was there I saw a bottle of calimagic all shiny and pretty looking. I grabbed a quart. Why? I wanted to get a brand spanking new bottle of fresh stock to run one final test on the holding reservoir. They reformulated the product.
Old formula: Ingredients: CALiMAGic is derived from magnesium nitrate, calcium carbonate, and iron DTPA.
New formula: Ingredients: CALiMAGic is derived from Calcium Glucoheptonate, Calcium Nitrate, Iron DTPA, and Magnesium Nitrate.
So they omitted calcium carbonate entirely and replaced it with Calcium Glucoheptonate. I knew I wasn't bat shit crazy here. The formula was bad, and they changed it as a result. Well, I'm probably still a little off my rocker but the formula was fucked. It had nothing to do with operator error. Changing a formula costs a lot of money in logistics, packaging, and distribution. They don't do such a thing just for fun. In any event I'll be running a 5 gallon bucket of maxi and the new calimagic formula. I'll report back in 72 hours what the condition of the reservoir is. At this fucking point I'll take photos
Edit: I previously incorrectly identified magnesium sulfate as an ingredient in the old formula. The only change is the omission of calcium carbonate which has been replaced with calcium glucoheptonate. The other ingredients remain unchanged.
