My buddy says this is what he uses:The important thing is to remember 321 is the ratio; Peters calls it out full strength 3.7g/2.4g/1.1g per gallon. I start out with my seedlings at 0.9g/0.6g/0.3g and then fairly quickly move to 1.8g/1.2g/0.6g or 50% for mid-veg. Late veg to beginning flower I go 2.1g/1.4g/0.7g and move up from there. It is quite easy to get burned tips and N tox if you don't read your plants; my last run and most likely this one I never went above 2.4g/1.6g/0.8g in deep flower before dropping off towards harvest.
I mix the Part A and MgSO4 together in a cup of hot water and the same with the Part B then add to my pitcher of water. I grow in soil (Roots Organic Green Lite which is coco based) and add literally nothing else.
I wouldn't give full strength to seedlings or small plants. Always start out at 25% and work your way up in increments to full strength as the plant grows and it's requirements increase. You'll burn the shit out of small plants or seedlings at full strength of any fertilizer. No rocket science. Just start out light and work your way up.My buddy says this is what he uses:
Part A 3.6 Grams per Gallon
Part B 2.4 Grams per Gallon
Epsom Salt 1.2 Grams per Gallon
Does that sound like a good place to be? He said his mix is usually just under 1000 PPM.
This is incorrect. With Jacks I've found through trial and error that I must run it full strength to avoid any issues. I feel all my plants the same EC, whether flowering, veg, seedlings, or newly rooted cuts. Check my signature if you want to see a timeline of this.I wouldn't give full strength to seedlings or small plants.

Full Strength from start to finish. KISSSo I am going to give this stuff a try.
Part A 15-12-26
Part B Calcium Nitrate
Epsom Salt
How many grams per gallon do you guys use?
My buddy and I use peat based soiless. Like Promix HP, sunshine 4 and Berger BM6 HP.Perhaps it depends on the medium. Hydro vs soil?
Your seedlings are all burned at the leaf tips because you are feeding too many PPM's for that stage of growth. Your clones are taking it much better and your large plants are beautiful. I understand it makes watering much easier, but please don't kid yourself into believing that you aren't burning the shit out of your seedlings. I have planted seeds in Fox Farm's Ocean Forest which is a very hot soil mix. Everybody advised me against it, but I planted them anyways. They were burned for the first few weeks, but then grew out of it. It largely did not effect my vegetative growth, but I did acknowledge I burned them and there was probably a better way to handle things in the future.Here's some photos of my garden I took yesterday. All plants are being fed full strength Jacks 321 with Mammoth P & Orca at .6ML/gal, and Fulvic at .4G/Gal.
As you can see no burn on any of the plants. The veggining clones in the second picture looked like the ones on the right just 2 weeks ago, fresh out of the aerocloner. But yeah man, when running jacks run full strength or you'll have issues with certain elements not being enough of the total EC when running it below full strength.

Where do you see tip burn on the seedlings? The Crescendo clones have yellowing from being in the aerocloner. The seedlings(MBxSF) have zero burn. Nothing has nutrient burn in that picture man.Your seedlings are all burned at the leaf tips because you are feeding too many PPM's for that stage of growth.

Go listen to the Jungle Boys who mass produce at the commercial level, they never change their feed schedule, every plant at every age get's the same food. I have not tried this personally but have heard a lot of people using this method lately.I wouldn't give full strength to seedlings or small plants.

i wonder what ppm they decided on to run from start to finish 700 -800ppm maybe ?Go listen to the Jungle Boys who mass produce at the commercial level, they never change their feed schedule, every plant at every age get's the same food.

Yeah I believe it's in that ballpark, they keep it super simple. 6" rockwool cubes, same food all the way through start to finish. https://www.youtube.com/watch?time_continue=332&v=AnWd2mHedK0i wonder what ppm they decided on to run from start to finish 700 -800ppm maybe ?
