Jack's 321 in soil

I’m looking at Jack’s 321 on Amazon and see it is labeled as hydro nutrients. Are these ok to use in soil?

Yes, there are a lot of us using these now. There’s a bunch of different ones, just make sure they’re labeled part A and part B. Epsom salt you can pick up for cheap at the grocery store or Walgreens/cvs.

They’re both the same except someone cut up the 2 lb bags and split them into 1 lb bags.

They do have a website, I just found it.

Yes they do but I couldn’t link it due to forum rules. I just wanted you to see what the bags look like. I ordered directly from jacks. Apologies, I should have mentioned that.

Looks like you have autos. I know autos like less feeding so I’m not sure on the frequency of feeding for Jack’s on autos. It is gentle so may be ok to go full on with it. @Nicky is actually running jacks this round so maybe follow along to see how he does with feeding.

I saw that last night and was reading. He is in coco so a little different but I’m following. @BobbyDigital thanks.

If your in soil, as I used to be before I learned how amazing coco is.
Then a soil sample or run off sample will be ideal as you need to know the tds, this will let you know what amount of nutrients are available in the soil /water.

You’ll want to feed once your soil has 1000 tds or less.
Once I had to start feeding in soil I would always water first, test run off then feed with that nutrient load in mind.
Otherwise your feeding blind

Ensure once you start feeding nutrients to give 20% run off to avoid a salt based ph root zone lockout.

@Nicky thanks for the info. I’ve seen/read that here on other threads. That’s what I’m planning on doing. Ph and TDS meter will be here this week. Still haven’t hit the go switch yet. I want to get everything set up and see space to get an idea how to put it all together.

@Nicky I read the info at cocoforcanna the other day and the idea of it makes sense to me but the daily or multiple watering makes me think twice. I sometimes am.gone for long weekends so idk if that would work.

Then you need to grow like me my friend.
I welcome you to the world of autopots.
I strongly strongly suggest you read this article (click the summerize button to shorten it to the important parts if need be, it’s located in the first post)
Then go buy a spring pot system and a buy or make a larger feed tank.

I leave for 8 days to two weeks depending on how many plants, time of year (summer they drink more) and size of plants.

This is my new journal, just getting started.

I’ve looked at them after reading and was curious. I am already reading that other thread as well. @Nicky

@Nicky I have a question (or a million actually). So I ordered some tribus and silica after reading other threads here and emailing back and forth w the jack’s expert. If I’m not adding nutrients to my ffhf/of mix for several weeks, should I be using the tribus? When and how much? When would I also use the silica?

@KPC I use tribus from the first water on to about the first day of actual flower. Same with silica but I keep using it for flower as it makes for a good ph up.
