Molasses and CalMag in organic grow

[GsC4477]

Im using unsulfured Blackstrap Molasses weekly when i water, I been told to add Cal mag to every watering ( since im growing in coco), so im wondering do I have to add CalMag to the water that gets Molasses? and do I have to add the Cal mag 1st to avoid lockout?

Do i keep adding Cal mag to the water until what point? im in later flower already.

You should probably first determine whether you need to be adding cal-mag at all, such as if you have well-buffered coco and/or base nutes that take care of Ca and Mg. You'll need to tell us about your water source (EC/ppm), feeding regimen, type of coco, etc.

In coco (usually Canna)/perlite, I only add cal-mag (or epsom salt/Mg) when there seems to be a need or otherwise just 2-3 times in later veg and early-mid bloom; and I foliar feed (using Transport), avoid messing with the coco.

Im just goin off what others tell me and it actually says it on the website for the coco i buy that it
"excels with cal mag/ added". I dont like using the product at all for a bunch of reasons, mainly its said to last 3 to 6 months, that's liquid cal mag, and that's per that manufacture ...

Id love to just add some epsom salt like you instead . problem is i paid for this 25 dollar bottle of cal mag.

I lack familiarity with the fertilizer and modified coco/perlite Tupur Gold product, but you likely shouldn't be adding significant amounts of cal-mag with every feed.

You should tell us about your water -- tap or well water (how bad), RO, distilled, etc.?

Filtered water? You'll want some calcium. You need to buy some before asking how much to use.

Fridge Filter dont remove minerals. just stuff like chlorine.
