That is about the ratio i feed at. 1/2 tsp / gal of Scotts Professional and approx 1/4 tsp/gal of cal nit. I am not exact though in my measurements so it could swing a little either way. I never did 1:1 bc i only use this mix in flower and that seems like way too much N for flower.

I started to lower the concentration of the Calc Nit about 3-4 weeks before harvest. I supplemented with some cal/mag i had lying around.

I have run a pheno 3 times now and the best round with her was the latest with Scotts + calc nit. I also just finished a dtc99 that turned out great as well! I think I spent approx $100 on the Scotts and Calc Nit but have enough nutes to last a lifetime.....literally!

If your running by-the-books Jacks professional:

That said I'd give a warning to those following what *mistress* said a few pages back. I wasted a good part of a year with huge problems cuz of the 1:1 ratio and "3-5g/gal calnit" info he had posted.

If I'm not mistaken, it's a suggested ratio of 1:1 by volume if you run Jacks and their CalNit that I believe contains some filler. That is, the same size measuring spoon of each. Each and every time.

The recommended dosage translates into an EC ratio of approximately Jacks:CalNit::1:.66.

By weight, it's Jacks:CalNit::3.6:3, (I did that math in my head... from my notes its 18.98:15.11).

Plenty of documentation of successful grows with no supplements, no changes, just EC 1.2 straight through veg and flower in the PPK thread (a constant bottom-feed wick system/with automated timed top feed).

A level 1/2 tsp. of Jacks 5-12-26 is approx. 3.6g.
A level 1/2 tsp. of CalNit is approx. 2.4g.

Just checked it on the scale. The Yara Liva CalNit is granular whereas the Jacks is almost a powder in comparison.

Is Yara the CalNit supplied from Jacks?

I am under the impression that it is not.

I am under the impression that the CalNit from Jacks has a filler that allows for the 1:1 volume measurement.

My ratio of Jacks:CalNit::1.25:1 by weight is based of the CalNit that is sold by Jacks.

If my impression is correct, and you use the Yara rather than the CalNit that can be co-ordered with Jacks measuring by volume, you will have a significantly increased concentration of CalNit over the specified formula.

If, however, you adjust your EC in the ratio above: that is add whatever volumes are necessary to make Jacks EC 1.0 and CalNit .66 per volume of water (i.e. adjust to your desired concentration by changing you RO added) you will be using a proven technique.

according to my measurements... jack's cal nitrate and the jack's 5-12-26 both weigh in @ 3.6 gram per 1/2 teaspoon. personally i use 1.6 jack's cal nitrate and 2.4 jack's 5-12-26 per gallon and have been happy with the results.

The Yara Liva is not from Jacks. I usually measure by weight.
You are using 1.25:1 Jacks to CalNit by weight. The JR Peters website says to use 1:.67 Jacks to CalNit by weight.(130oz of Jacks to 86oz of CalNit for 1000 gallons.)
It seems like that is a quite a bit more CalNit than the standard formula. I thought the 1:67 ratio was by weight and not by ec?
I've only been using Jacks a few weeks and I want to make sure I'm using it the best way.

Peace.

Strange all the way around.

I did ten measurements each on arrival of as uniform volume as I'm capable of, and weighed them... and did averages.

I then matched volume measurements, and dissolved into water with an EC meter.

That's the source of my numbers...

Strange inconsistencies all around.

I assume Jack's Calcinit is a powder while Yara's Calcinit is prilled, so no wonder there are differencies.

ImaginaryFriend · 06-23-2011, 03:06 AM

Jack's CalNit is prilled too...

orange juice · 06-23-2011, 04:09 AM

weighed my prilled calnit from Hydro-gardens and jack's.

I got 5.4g /teaspoon for calnit and 5.7g/teaspoon for jacks.

My scale isn't a great one but seems close enough... at least that it's not .66 to 1.
