Adding Cal-Mag to my nute schedule?

[RandyL]

I grow in FFOF dirt, with FF nutes. Grow Big, Big Bloom, and Tiger Bloom. My next grow will be Bubba OG with a few GDPs in there as well.

I'm also using the Open Sesame, Beastie Bloom, and Cha-Ching supplements in flowering as their schedule says to.

I use RO water that I PH correct after adding nutes, and I also use blackstrap molasses at the rate of 2 tablespoons per gallon.

I recently started hearing from some people who grow in my area how I should be using Cal Mag, as my RO water doesn't have those things in it.

Would Cal Mag help, considering the nutes I already use? I'm supposed to give it every watering/feeding? Would I do anything to my molasses feeding schedule once I start using Cal Mag?

Are any brands of Cal Mag better suited for my growing conditions better than other brands?

Thanks!

Well its hard to say. I find that sometimes my plants need cal/mag starting at about week 4 of flower. I usually wait until I start seeing signs of a cal/mag def before adding cal/mag. You dont want to give it too much Cal/Mag because having too much might lock out something else.

If your using RO you need calmag, any brand will work.This wont change how you use your other additives but it will raise your ppm so you will have to adjust your nutes to get the number your looking for.

Gluck....

Adding powdered dolomite lime to your mix will not only supply cal/mag, but also keep it buffered to the sweet spot of 6.5-6.8.

~$5 for a 40# bag at Lowes.

But then all the high priced additive companies will suffer!

Why run RO in dirt anyways? is the water source really that funky?

Edit: oh never mind...LA water, nough said.

I'm in Los Angeles. Yes, the water is not the best around here.

Right on the money DD (I'd rep ya but I gotta give more out before I can rep you again). If you are growing in soil, this is what you want to do...
