CalMag

mobiledynamics · June 20, 2018

So the directions on the CalMag Supplement say use at every watering ;-)

Anyhow, chucked away about 10 tomatoes so far with BER.
For those using CalMag in your container routine, what's your CalMag Watering Cycle. Every time you water, Once a week. Whenever the moon rises past 12 oclock.

I've been using 1 teaspoon per 5 gallons of water every evening after the plants are in full shade. That's the amount to use on the package.

ALS. foliar or liquid supplement.
CalMag is a LS. I see they also sell dedicated Foliar concentrate as well...

AlittleSalt · June 20, 2018

I read this wrong - it's magnesium sulfate that I am using.

I apply as spray 3 times a week I also used it in my potting mix along with bone meal, Epsom salt & garden lime in my grow bags that were used for tomatoes & peppers, I've had great results.

Any reason you are foliar feeding vs. liquid feed ? Root intake is much more than foliar feeding - never was a fan of FF even though manydo

I've been using ff for 2yrs now. Talk about a learning curve. I noticed that flushing is very important. I do have a recycling system, so it helps. Salt buildup is an issue, it seems most liquid nutrients have this issue. I am not thrilled with my decisions or the outcome. But my plan is to follow the schedule using ppm, ph meters and flush my system and see how it goes. The other thing I have noticed is different varieties have different needs and perform accordingly.
I hope that helps,
Tom

I also liquid feed I just forgot to mention it, I do it once a week

I've done 2 container soil drenches. Cumuative up to this Sunday, I've picked a hair over 2 dozen + with BER.

Soil drenches primarily because I just want it to be taken up between just keeping the current container medium moist - currently it's on a double duty schedule *3 times when it hits 90+*. My mix is a tad too coarse this year. Since it leeches too quick, I'm thinking the less is more approach with the soil drench is better than watering it in.

Man, I should have done the CalMag once I started seeing fruit. Hate chucking out good tomatoe's.

You use it every time you water, 3-5ml per gallon. I never get BER. Most people seem to learn best by torturing themselves to success. I was one of those too, then I wore out and started following the directions that the guys in the loop hand out. WOW... I love walking my plants now.

Grr. Should have been on this once I got flowers

In total up to yesterday , probably have chucked away about 3 dozen tomato’s.
Edit - make that 36+ - just plucked another 5 to be tossed.
Hopefully the cal mag feedings will mitigate this

I use it once per week in my Earthboxes, but they have Tomato Tone and dolomite added already, when replenished for the new season, so my cal-mag is supplemental.

mobiledynamics · June 27, 2018

Same here, Dol, TT and CRF that has cal/mag in it. I don't believe TT does anything in my containers except for the peace of mind. Hopefully this year won't be a bummer blossom end rotter for all.

Off topic or on topic. Man, this stuff is just slighty gross when dried. It dries up to a darkish thick dark brown gummy residue. Ha, I feel like I'm dealing with p0op when I'm unscrewing the cap

Odd. What is the content? I guess it has iron EDTA? That would be the only explanation for the colour. It should contain either sulfate or nitrate of Ca and Mg which don't have a colour.
Not sure why they contain iron, it's boron which should be coupled with Ca against BER.

Does your water contain any Ca? What is the ec of just water? It's unusual to have so much ber.
