So talking with the local athena rep, they are switching things up, like running core:grow in veg at 50:50 so
Take your total ml per gallon of both you use, then change it so it’s the total but equal volumes of both core and grow.
So for us it’s 24/24 ml/gal
Then in flower starting day 1, go to 30:70 core:bloom 14.70/34.30 ml/gal
Start of week 6
20:80 core:bloom 9.8/39.2 ml/gal
They told me the same thing, I’ve been thinking about lowering the calcium nitrate adding some calcium chloride and micros to make up the difference from the lowered calcium.
It has been a real game changer in the physical look of the plants in veg, we don’t add anything currently.
About to do the first room flowering using this method, but so far so good.
i had heard about the change in ratio for flower but thats the first i have heard about the vegging ratio change, thanks for the heads up.
You’re welcome, he said they are doing it to stack nitrogen more in veg then remove it at the end of flower, that was the reasoning… the transition was flawless and veg plants to me look more healthy than they already did.
@Cryo13 stock tank 2,5lbs for 1 gallon?
Do you have a link ?
I’ve heard a finisher is coming so to avoid the nitrogen when doing 80/20 the finisher be basically the calcium one of you mentioned. As I was gonna buy the cal106 I been seeing but waiting for this fade finisher
Max is 2lb per gallon.
I calculated error or not
24ml/24ml N 240 P 52 K252 ça 258 mg45
c14.70ml/b34.3 N130 P112 K433 ca 160 mg 65
c 9.8ml/b39.2 N 87 P 128 K 494 ça 105 mg 75
If you go way further up this thread there’s an actual lab analysis from last year. I’m not sure if they have made any changes since then or not.
The Ca:Mg ratio is at least as important as the macros you listed. Don’t overlook it.
Technically it’s not exactly 2 lbs per gallon,
You would take half a gallon of RO then mix all 2lbs into that then stir, then once dissolved you add RO water until you reach 1 gallon.
So with salts added it equals a gallon.
10lbs of salt = roughly 1 gallon
@Cryo13 I have calculate 1ml stock solution =0,24g core or bloom or veg
I’m 28 days into bloom

I would like to test the athena recipe i have scary to burn m’y plant
I can’t speak for other recipes of athena, however the one I posted is not burning plants.
Generally with athena if you getting burn using one of their formulas at 3ec it’s due to your drybacks being to large and it stacks the ec in your substrate which in turn burns the plants.
I recommend the terros 12 sensor and you can download Zentra Utility to get controls over the settings to get it set to pore ec, then keeping your plants healthy becomes alot easier to understand.
Having a data logger like the zl6 would be extremely useful if you really want to get some useful data.
@Cryo13 thank you
Athena ag récipé for cropsterring style no other style
“trust the program!”…, no not that old one!, this new one!.
but seriously this is just a band aid isnt it?, with that big a change to the ratios surely they are going to need to reformulate core to adjust the calcium and the micro’s?. but with the different and constantly changing ratios they now advise i cant see how they can find a good balance for it short of seperating it into its own product?.
In the end companies like Athena want to provide a solution that works perfectly for everyone. Sadly given the variety in growing methods, strain genetics, environmental conditions, etc, this is not possible. Any fertilizer provided massively will always be close to optimum for some and very far from it for others (a reason why there are a million fertilizer products for cannabis and not just one).
I believe those with experience doing formulations for different clients, such as @emdub27 and others, can probably attest to this fact. In my personal experience, optimizing formulations for specific clients based on quantitative information has never yielded the exact same formulations. Often the differences have been quite substantial.
The modifications in feeding schedules probably reflect what is working best for their highest paying clients or their own internal research. The issue with going with a company like this is that you’re always “along for the ride” and if the past formulation was great for you and they change it because it worked better for another group of people then you’re going to be in a worse situation. If they suddenly decide they want to charge 3x the cost and you already have your entire operation committed to them, it’s also going to be very hard for you to change products.
For large and profitable grows, the use of in-house made formulations - or at least contracted to be made by another party with an outright known formulation - that won’t be changed is important for future survival, reproducibility and continuous self improvement.
I’ve shone on this topic many times and other topics.So I can’t help but sign up to thank everyone here I’m from Thailand and I got a lot of knowledge in future4200 that Thailand doesn’t teach. It’s really deep and I know about brix. Suddenly I ordered Emdub refractometer. You are our light. I love to see you narrate and respond. Every time I read it is wonderful. You are our teachers. And you made me a better planter. I started planting 1 year ago. Before marijuana in Thailand was legal This is my first run in coco and it’s season 3.in my life
