How to add Calcium + Magnesium? (calmag)

Coco actually loves feed/water/feed/water.
It hold nutes really really well so you can save some cash on nutes by alternating and it keeps salt build up at nearly non-existent levels.

And as others have said that Canna Liquid Magnesium is not cal-mag. I mix actual cal-mag right in with my coco nutes. I alternate between 2ml per gallon and 4ml per gallon @ every other nute batch.

See, there's another interesting working ratio! might want to watch the K at that ratio.

I kinda was partial to 3-1-2 all through the early years for my starting ratio (not a lot to choose from back then - synthetic wise).... I got "taught" by an old "hippie" in the 70's. he showed me how to mix organic ferts to my NPK liking...
Naturally I just had to try synthetics for awhile...Went back to the organic I built till the first Hydro 3 parts came along and went back into synthetics for a long, long time. Covered the bases (still doing org. for my personal during this) and did hydro, back to soil, new brands came out did both....

Along about 2010, I began to phase out synthetics but, was still trying new brands for stores and such. About mid to late 13 I left the last synthetic sit on the shelf and went back to 100% Org. I still get bottles of this and that from some makers to test. They go to my close friend and employee,Tom-tom. She try's them out and sends back results by company email.

I don't see either Cal or Mg having neg effect if used right. Mg can be given rather heavy, mid to late bloom in the form of Mg Sulfate (along with a solid carb source - minor amount) and do some real increasing of trichomes and terps! K sulfate works too as testimony to things like "The Rock Resinator". The thing is, with K sulfates the terps become heavily citrus (lemon). It does effect the nice Berry and Pine smelling strains to be overpowered by more lemon or fuel smells and tastes......It does do the increasing BUT, I don't like the cost!

You have sparked an intrest...but the K sounds like it might be a tick high for use before late veg or right before the flip....K overuse will stunt plants and hurt yields - in veg. The sweet spot is "large" but, like any "pushing". The fall off from hitting too much is very steep. The plants will really "color" up with high K use!

The exciting thing now (for those who understand how to) is that we can get individual nutrients and "build" our own synthetics, with what ever ratio we want! There are a few doing that here. Look in the DIY section. Drop a cpl of them a line and chat that up!
I do see them on the boards too.

Woh, so are you saying introducing more CalMag towards mid flower will increase resin production and flavor profiles? I'm growing Lemon Kush right now and would love to bring out the heavy citrus flavors it reports to have.

Nope, not Ca/Mg!

Mag Sulfate and a carb, in proper ratio's.

Here's my formula for a great Terp and trich increasing supplement. Costs less then a buck per gallon to make it! Botanicare Sweet raw is over $65 a gallon! Mine is a better ratio (50% more carbs) and works better I feel...

Follow the formula given the first time and feel free to try it differently in later runs. That formula worked best for me when I ran synthetics...

Use organic Epson/sugar and try it in organic runs!

8 TBL Epsom salts
1 1/2 tsp DARK BROWN sugar
1 gallon RO water
1 opaque gallon jug

Bring 4 cups of the water to a rolling boil
Add the Epsom and the DBSugar
Boil for ,, oh 3-5 min stirring constantly

Pour the hot liquid into the opaque gallon jug with the other 12 cups RO water already in it and shake well to mix....

Bingo! $1.00 a gallon *new and improved* Sweet Raw.....

This applies to synthetic and synth/organic combo runs. The feeding is done everyday at lights on with just enough solution to carry it to the next day at lights on when plain water is used.

10ml a feeding starting at 2 weeks b4 the flip

15ml at the flip and till week 4

20ml from week 4 till harvest

That's what worked the best for us so far....in soil......I'm going to do an Ebb hydro run in a cpl of months and will try the say formula on that then.....Don't know why it won't carry over with the same performance...

Alternate feeding sched =

5ml last 2 weeks of veg
10ml at the flip
start of week 3 up it to 15
start of week 5 20ml till harvest

Nice so I can run this alongside my Dyna Gro nutes then? Definitely going to screen shot this. How long does this mixture last in the jug?
