Cal-Mag needed for Distilled or RO water? - Growing in Coco Coir - International Cannagraphic Magazine Forums

do i need to add Cal-Mag to any of these types of water when using Coco?

i would have to say yes you need cal mag and some thing that contains trace elements, unless you find nutrients that are made for use with ro water. canna coco A+B for example are made to be used with tap water. they count on the fact that you have some calcium as well as trace elements in the tap water.

cal-mag will not give you all the trace elements. you get calcium, magnesium and iron but not much else like sulphur and zinc. you would be better to get an organic tea blend like kelp which has it all. IMHO.

I have been using canna nutes with distilled water mixed with RO water...the ppms of the 2 waters mixed is like 15 ppm...is it ok that i'm using canna coco nutes with the mix of RO/Distilled?

it's ok for a while, but sooner or later your plants will show problems. use 50% tap water and 50% ro water, then you still have the trace elements and calcium your plants need. keep the ph at 5.8 and you will have enough mg too this way.

Didn't know canna a+b needed to be mixed with tap water... learn something new everyday..

if your worried plants arnt getting what they need, Use the canna buffer has cal/mag to buffer coco and flush during the grow, also use the trace mix at low dose in all res mixes..

I use Ro water and dont often need to use these products but would guess that using them early in the grow gives best chances of a trouble free grow..

knna that's interesting and nice to know. I used 50/50 tap/RO for my grow and only got into trouble when I tried Cal-Mag+ for a couple of days. I'll check and see how much Ca and Mg A+B provides and think about trying to leave the tap water out of my grow next time. Got decent results this grow though, so I might just not do anything diff, hehe.

Nice to know though.

Peace

Can I just add dolomite lime to my distilled water for cal/mag?

I had some calcium deficiencies on some of my plants using Canna Coco A+B and tap water that came out at 30-35ppm. Added a little bit of Cal-Mag+ and the problem was solved.
