Cal mag or nahhh?

yabbadabba2 · Nov 27, 2017

What up guys !

Quick question I’m running my first coco grow and needed to know if I add cal mag to every feed. I have been reading about cation exchange capacity and read that it stores nutrient in its cations such calcium sulfate, magnesium, and potassium, and etc. I’m using a pre hydrated brand of coco from Walmart and was wondering if it still has cal mag stored in its cations from the manufacturer. No details about this on the bag so I turn too you guys. Thanx

Are you using RO water or tap water? If RO water I would say yes. If tap, maybe not.

My tap water is 0ppm
I know I'm lucky at my new place
I haven't used calmag until week 2 of flower plants started to show def
I would do quarter to half strength every other wayer

as cal and mag are removed in ro, i would use full strength every feeding. if you are waiting for deficiencies, you're late...

If cal mag is stored in the cations would adding more at every feeding cause lock out of other nutes?

My set up is recirculating drain to waste. I add 1tsp per gal of cal/mag, I feed pretty much everyday and flush every 2 weeks. Just sayin...

4gal smart pots about 3 gallons of coco and there about 15 day old clones and I water every 3days because pot looked a little big . Should I be feeding every day now?

I read if you get a decent amount run off no need to flush in coco is this true?

There is no need to flush in any type of medium unless you screw up drastically.
