Hey folks! I’m on my first grow and really don’t know much yet. So please bare with me.
I’m growing some autos in coco and using Jacks 321 just about everyday. 1 of my plants is looking light green and I was told to use Cal Mag. Well now I have no idea how to use it.
Do I add the recommend amount to the Jacks or am I mixing a separate batch of just cal mag? If separate do I alternate feeding Jacks one day and cal mag the next? Should I also spray the leaves with or just water the roots?
It seems that there are a lot of post but none that break it down completely. Any help is appreciated.
You should not need to use calmag if your running jacks. The part B (cal-nit) should have all the calcium you need. Do you have a pic of the plant in question you can post ? And what are your dosage amounts and ph for the jacks

At your next water/feed bring the ph of your jacks to 6.0 and water till you get a good amount of runoff coming out the bottom of the pot . Your ph is too low and it looks like you’ve locked out some key nutrients.
Your mixing your jacks in this order/amounts
Part A - 3.6 grams per gallon , when that’s fully dissolved
Adding Epsom salt - 1.2 grams per gallon
When that’s fully dissolved
Adding 2.5 grams per gallon of part B.
Let it sit for some time and then take your ph readings and adjust to 6
4.6 is about right with distilled or RO water. Now you need to add ph up to get it into your 5.8-6.0 target. Cal mag is basically 2 of the 3 ingredients of Jack’s. Cal nitrate and epsom salt (magnesium sulphate).
@Watt-Sun@Myfriendis410@BobbyDigital hey guys couple questions for ya. So i’v been using jacks 321 & CALiMAGic for +10 weeks now, using Tupur CoCo - perlite outdoor in 7gall pots. I ran out of part B few days ago n that’s when I realized I Fd up. I didn’t realize jacks had enough cal mag already. I ordered more part B and they all look good so far. So I should cut the CALiMAGic out or part B n Epsom salts, what would be better, or should I stay with using both like I did for 3 months now?
Just discontinue the cal mag. Keep using Epsom per the 3-2-1 recipe. I would start adding silica, especially for outdoor plants: disease protection, stronger stems not to mention silica is necessary for trichome production. I run silica with Jack’s from the first feeding to the last.
Can’t disagree with @Myfriendis410. Drop the calimagic. If you need more cal, add more part B. If you need more mag, add more epsom. Adding silica isn’t as crucial in soil but in coco should be part of your nutrient regimen.
Was reading this post because everyone and there mama is saying go with Jacks123 but i had already bsught FF trio and dirty dozen…im curently adding calmag also…do i need to stop calmag with ff? Appreciate the help in advance.
