Appreciate you guys…
Day 9 of Flower
..New res made up- same as last time 5.9 pH 1.8EC
Looking killer brother is that Chem Chillz a polly??
I was going to ask the same question!
![]()
I thought it was supposed to be a Slush x lol excited to see how wicked it gets haha
@kaptain3d Haha beat ya to something finally buddy ![]()
Usually we don’t let them go, but this one is close enough to the light ![]()
Those double buds are always so dam cool to see just so unique imo
If we can take this run to term, it will be interesting to see what happens. Slush usually really starts kicking into gear around week 4-5. Curious to see if those tendencies carry.
I hope everything works out for you guys…
Hey @Low so im going to be getting some jacks A and B soon. Could you walk me through your process of how you make up a batch to try and save me some time and money? I think i remember somebody mentioning not wanting to mix it too quickly or something? Dont quote me
I’m thoroughly lit, but yeah I’ll share what I do.
Are you using Epsom also or just 2 part?
@Caligurl
Thank you, we are doing our damndest to get things worked out
How much would the epsom cost for a 2.2 lb bag of A and B together?
Finally about to start working again so i dont have to be super cheap with everything soon enough.
I wouldn’t buy Epsom from jacks or any nutrient company. You can get plain Epsom for $3-$5 for 5lb at most places. Unscented pure Epsom. Preferably food grade, it in all honesty it doesn’t matter.
Using Epsom does provide a better balance than just A and B alone. But the biggest thing for me, is it saves me on part A
Edit
Coco, soil? If coco, perlite ratio, or straight?
Straight coco for now until i get the income and get caught back up on bills. I hate to do this to ya since you’re litty but run me through epsom and no epsom if youre willing.
I tried to write it up and then consulted my AI… I can barely see straight. ![]()
Jack’s 3-2-1 Formula Components:
• Nitrogen (N): 5%
• Phosphorus (P₂O₅): 12%
• Potassium (K₂O): 26%
• Micronutrients: Includes iron, manganese, zinc, copper, boron, and molybdenum.
• Nitrogen (N): 15%
• Calcium (Ca): 19%
• Magnesium (Mg):
• Sulfur (S):
Mixing Ratios for Jack’s 3-2-1:
• 3.6 grams of Part A
• 2.4 grams of Part B
• 1.2 grams of Epsom Salt
• Per gallon of water.
Nutrient Contributions per Gallon:
• Nitrogen (N):
• From Part A: 3.6g × 5% = 0.18g
• From Part B: 2.4g × 15% = 0.36g
• Total Nitrogen: 0.54g
• Phosphorus (P₂O₅):
• From Part A: 3.6g × 12% = 0.432g
• Potassium (K₂O):
• From Part A: 3.6g × 26% = 0.936g
• Calcium (Ca):
• From Part B: 2.4g × 19% = 0.456g
• Magnesium (Mg):
• From Epsom Salt: 1.2g × (~9.8%) = ~0.118g
• Sulfur (S):
• From Epsom Salt: 1.2g × (~13%) = ~0.156g
Understanding the 4/2 Formula:
• 4 grams of Part A
• 2 grams of Part B
• No Epsom Salt
Nutrient Contributions per Gallon in 4/2:
• Nitrogen (N):
• From Part A: 4g × 5% = 0.20g
• From Part B: 2g × 15% = 0.30g
• Total Nitrogen: 0.50g
• Phosphorus (P₂O₅):
• From Part A: 4g × 12% = 0.48g
• Potassium (K₂O):
• From Part A: 4g × 26% = 1.04g
• Calcium (Ca):
• From Part B: 2g × 19% = 0.38g
• Magnesium (Mg) & Sulfur (S):
• Not provided without Epsom Salt.
Key Differences and Considerations:
• Potassium Levels:
• The 4/2 formula provides slightly more potassium (1.04g) compared to the 3-2-1 formula (0.936g) due to the increased amount of Part A.
• Magnesium and Sulfur:
• The 3-2-1 formula includes Epsom Salt, supplying essential magnesium and sulfur.
• The 4/2 formula lacks these nutrients unless Epsom Salt is added, potentially leading to deficiencies.
• Calcium Levels:
• The 3-2-1 formula provides more calcium (0.456g) than the 4/2 formula (0.38g) due to the higher amount of Part B.
• Nitrogen Levels:
• Both formulas offer similar nitrogen levels, with 3-2-1 providing slightly more (0.54g) than 4/2 (0.50g).
Pros and Cons:
Jack’s 3-2-1 Formula:
• Pros:
• Balanced Nutrient Profile: Suitable for various growth stages.
• Includes Magnesium and Sulfur: Prevents potential deficiencies.
• Cons:
• More Components: Requires precise measurements of three parts.
4/2 Formula:
• Pros:
• Simplicity: Involves only two components.
• Slightly Higher Potassium: May benefit specific growth stages.
• Cons:
• Lacks Magnesium and Sulfur: Needs additional supplementation.
• Slightly Lower Calcium: May require adjustments depending on plant needs.
Conclusion:
While the 4/2 formula offers simplicity and a marginal increase in potassium, it lacks essential magnesium and sulfur, which are crucial for plant health. The Jack’s 3-2-1 formula provides a more comprehensive nutrient profile, supporting plants throughout various growth stages. For optimal results, especially during flowering, the 3-2-1 formula is generally recommended.
Holy "F"ing sh!t!!!

That info is what I needed to complete my Jack’s nute calculator app!
Score!

How accurate is your Ai?
It depends how much I probe it. Make it correct itself. Basically I have to explain the nutrients up front, make it learn from the website, and then it can compare the ratios I ask it to.
Sometimes it’s crazy off the wall, and I have to ask and point things out. I try to put it in a position where it realizes it’s wrong and re writes. I had to correct this response above several times before it came out the way it did. It has to learn the product.
That was beautiful. Thank you so much. I really appreciate that especially since you cant see straight. Lol
Do you just put in the part A then part B then epsom? Or do you wait inbetween each part to let it settle and disolve fully?
@TrichromeTay
With all that said, I had success with every ratio I’ve tried through jacks, full strength, 321, 4/2, 3/2… just had to concentrate them to get the EC where I wanted it. Which often times led me to using more of part a, than I would with the full strength.
My current ratio is 4/2/1.5 and it’s going wonderfully staying between 1.7-1.8 EC early flower. Started with full strength.
You have to mix them independently until fully dissolved. The problem I’ve found with part a is that there is always sediment left behind. So i filter part a. Since I’ve been doing that I’ve had 0 reactions. With that said bucket by bucket it doesn’t seem to have an impact if left unfiltered. Weird, but I suppose it would take some time to react.
Epsom until fully dissolved
Part a until fully dissolved
Part b until fully dissolved
pH adjust,
Ideally you’d want to have a container of water and each one dissolved in water separately. Then you add the parts one by one.
So if you have 5 gallon bucket you are doing the mixing in, fill it with water and pull water from it using small containers, dissolve the parts in those containers and then add, mix, add, mix, etc.
Bet. I feel like ive already done this before now. I really appreciate you making this easy on me. Last thing i want to do is butcher gallon after gallon and be too stubborn to figure out why by asking someone but be too stubborn to give up as well. Lol
