Thanks for teaching some of us about Mulder’s chart. Very nice!

Tissue and sap data I have on healthy almost perfect plants of various cultivars only vary by roughly 10%.
What will vary widely are the ratios in solution to achieve the healthy analysis. IME cultivars that have similar structural traits tend to be very similar feeders. Comprises are being made if Jack and Afghani are being ran on the same fertigation solution. It’s important to note that I’m usually correcting deficiencies that most people can not notice. I couldn’t notice them 2 years ago with the naked eye due to limited lab access. Now I can tell that leaf shape will start changing before you are able to spot what most people will recognize as a deficiency or toxicity.
In my facility we flower 12 cultivars at a time on the same fertigation mix. They get along well enough. A couple are perfect, a couple aren’t, but the herd is healthy.

Today I learned the plant products makes a cal nitrate product called purecal that is 13%no3 and 18%Ca. Not as concentrated as Cal Prime, but it is Nh4 free and has a similar N:Ca ratio. Plant products being in Canada may make it an easier option for Canadians like @Medicine.grower

are there cheap ways to measure ratios of nutes in runoff?

Thanks for that, I was actually reading about their products last night as I can get wholesale pricing on them, I’m trying out the Athena right now and so far so good.
I might have to order some of that to try with the jacks 5-12-26. Even if the Athena works I would like to find something with the same numbers that’s a bit cheaper.

Sure is just need to dip you ec meter into your run off, when I want to check I put a saucer under a few plants to collect run off then I check ec/ph.
im saying what ratios of stuff is in the ppm of the runoff? I dont do runoff I use coco and saucers and pbp . In the end i usually do have high runoff but it seems a pain in my ass to do runoff. I need to do real grownng in a warehouse or greenhouse. I do the humboldt shuffle all the time and my garden looks like it was never there giant trays seem to be difficult. I bought 2 x 4 trays from botanicare and they stink and have cracked.

Send a sample out to your closest ag lab. I personally never have runoff analyzed. Long water change recirculating systems get analyzed weekly.

Their chelated micro product is fantastic! I like Plant Prod as a company.

I’m getting what look like sun spotting on plants and I’m not sure if it’s from the cal acetate or what. Still adding it… growth seems to have sped up a bit.

I got that too. If it looks like a magnesium issue, I upped my base a bit for one feeding and it went away.

Do you guys know anyone using there full mj line? 5x the buds 80% cheaper, sounds good on paper lol.

Cal nitrate is a standard of the greenhouse industry. I use it on every plant I grow outdoors, at least in seedling and veg. What is the problem with it?

I moved one clusterfuck of a facility off of it. I think the way it was being used was a bigger problem than the actual nutritionals. They would literally fertigate one part per day on a rotation, so one day bloom, one day cal kick, one day spike and repeat.

During bloom in a low vpd environment (overly humid greenhouse, outdoor in the pacific northwest) it can be hard to get sufficient calcium in the plant without also having excess nitrate. In most environments where you can reasonably control the vpd standard calcium nitrate works fine. Increase vpd to get more calcium absorbed…

lmao Ill bet they thought they were doing something special too
I’m using florapro GH their new powdered line.
Seems to be tits for consistency on large scale
With some addition of spraying fish fulvic and verde in rotation

I got two bags of the purecal on order, I’m going to do a side by side with that and jacks 5-12-26 and the Athena pro line to compare.

Nice. Approximately what is fertigation costing you per gallon? You could pretty easy clone whichever you like with one fertigation analysis and hydrobuddy.
