Ok let me me get this strait, This is a recipe for a liquid concentrated 2 part/A&B.

232 grams of Jacks + 1 liter of water = part A
156 grams of Calcium Nitrate + 1 liter of water = part B

Feed at a 1:1 ratio per gal.
10ml of each A/B will give you EC 1.2 ( 600ppm @ 0.5 / 840ppm @ 0.7 )

So how would I feed? (Please copy and past with ppms or mL filled in)
--- Veg---
Week 1: ?
Week 2: ?
Week 3: ?

---Flower---
Week 1: ?
Week 2: ?
Week 3: ?
Week 4: ?
Week 5: ?
Week 6: ?
Week 7: ?
Week 8: ?
Week 9: Flush ( Hydro )

I'm also reading that people suggest cutting off the Calnit by week 3 or 4 of flower.

Sorry guys but it gets kind of confusing when some people start throwing in different numbers around.

Put the jacks into the one liter bottle and fill with RO water till almost full. Shake the shit out of it, then top off to one liter. Do the same with the calcium nitrate.

For plants under 10 inches use 5 ml of each per gallon of nutrient mix. Use RO water.

For plants bigger than 10 inches use 10 ml of each per gallon of nutrient mix. Again use RO water.
PH both mixes to 5.8.

Run this all the way till one week before harvest. Then just run water till harvest.

The 5 ml per gallon should be about 0.6 EC, and the 10 ml will be about 1.2 EC.

This will work with most set ups. Some strains may require some more and some will require a little less. High CO2 usage will require more.

You can add extra stuff but this will get good bud in the end.

I run 1.2 ec from rooted clone to flush. I flush for one week, this is in coco.

360 ppm pro
240 ppm calnit

Everyone gets the same feed be it veg or bloom. So damn easy and cheap

Does Jack website ships discrete?

if not, does anyone know who else sells jack hydro and ships discrete?

[audiohi]

Coming from the website, it comes in a box. Nothing to worry about. If I remember correctly though, it came as a freight delivery. I don't know if that's discrete enough in your area, but I don't really consider it a problem. Worst case scenario, you'll have a fedex big rig type truck make your delivery.

My jacks just game in a plain brown box.

So I've read over this thread and have seen a bunch of different answers to this question but can anyone just tell me the the jacks nute to purchase or link me to it. I know the cal nit but i need to know the nute that works best in coco. Thanks

Here is a link to their nutrients:

I use the 5-12-26 from the link above. I buy YARA calcium nitrate locally at $22 for 50 pounds. I have listed above the mix I use. It is for coco and uses 10 ml of each per gallon.

So I know most of you guys are growing in coco. I'm trying to figure out what exactly I should use for growing in soil. I guess maybe I'm just being over anxious.... but I just want things to go right. I have been having problems with another fert line I have been using. Stuff comes out alright but its one of those auto phing lines. Their customer service still hasn't gotten back to me after some weeks so I decided its time to change it up. I don't like that I am not 100% sure of whats going into the soil. Mainly I'm curious about these things:

1. I have read that people were mixing the 5-12-26 and the 10-30-20 and calnit and epsom which supposedly comes out to basically the same as Maxibloom (which I have never used but i have heard its nice other than apparently it doesn't like to dissolve.)

2. Just running the 20-20-20 through veg then going into 10-30-20 when flowers start. (someone suggested on my post about using jacks in soil. He copypasta something someone posted in another thread but can't find it so far.)

3. Also I read on one or more forums that people alternate weekly from 5-12-26 and 10-30-20. (are they doing this through out veg or just in bloom?)

To sum it up.. I feel like I have asked in enough places. I guess I'm just looking for other people that have had success in Soil using any one of these. Lots of people including people I know use it in hydro (coco) but my room is going to be soil for a couple rounds and I'm tired of having problems with my other fert line...

Ps. Also what do you guys think about feeding schedule with any of these methods? My guess is once a week ranging from 600-900+ gradually.(until signs of curling)

Can you tell me is it okay to run Jack's in hydro when I have 24celsius~ reservoir temps and I am managing it because I am aerating it and using Liquid silicon from Growth technology.
I can't manage to buy a chiller because I have 2 separate reservoirs so I'm thinking is it okay to use Jack's with for exammple Ag16H silicate powder you can order from the same sites with Jacks? If so at what rate to use? I'm asking because I think there might be potassium overdose?
