Jacks (JR Peters) nutrients

Unripped

If you're planning to use it for a crop you'll be earning money with, it only makes sense to get a TDS meter so you can measure your nutrient strength and a pH meter so you can manage your acidity levels.

GET GOOD ONES, CHEAP INSTRUMENTS ARE A FOOL'S ECONOMY!

That's free advice, worth hundreds of times what you paid for it.

EDIT; a TDS meter will still help you in soil, so you can measure and control the nutrient strength going in and measure the strength of the runoff coming out.
I'm using jacks currently and have been for some time. What value comes from checking the TDS of the runoff?

It tells you what conditions are like inside your rootball. If the EC level climbs into dangerous territory, your runoff will tell you.

If you don't feed them all the time you will never have a problem with it. Water in between and low dosages will grow you nice green healthy plants from start to finish. The trick is to slightly underfeed them and then you will notice they need food so you give them a nice healthy shot, wait a couple waterings and then give them another shot just for the fuck of it. Then wait a little bit bam do it again.

Shit is easy man, I have never had a problem with peters being over the ppm I usually water at like 800-1000

MKP = monopotassium phosphate,
0-52-32

Has nothing to do with calcium. Use at .25 gram per gallon in bloom.
Oh, I was thinking you were talking about MOST from JRpeters. I'm just starting to get into the recipes for this stuff. Been on the fence for a long time on Jacks, decided to take the plunge.

The thing about these big bags of mixed dry nutrient salts to watch out for is that they settle. You want to mix a large batch into a stock solution and then use that in order to eliminate the likelihood of weird nutrient imbalances cropping up randomly...

No need to do it for MKP, calcium nitrate or epsom salts because none of those is a dry mix.

I am switching to Jack's and just received 1.5 lb. of citrus 20-10-20...and 8 oz. each of 20-20-20...10-30-20...and 30-10-10.
It cost (factory direct) $26.76...

I just fed them yesterday for the 1st time Jack's 20-10-20 citrus 1/4 teaspoon...feeling my way through the stuff right now.

At $26.76 compared to your AN $150...who cares if you buy more stuff than you need...
$26.76 is not much more than one bottle of FF stuff I was using that has expiration dates...

I hear some run the citrus beginning to end. Since the other stuff was reasonably priced, I bought a little of each. If I don't use it inside, next years tomatoes and peppers will get to try it. Lol.
I B 1 of those people. Last three grows. The latest I pretty much went 1/2 tsp, per gl of the citrus from the time they left the party cups with 1/8+ tsp epson started a week before flip..both continued until now, day 57 of 70 day plants. Will go straight water until finish.

Hello guys I finally jumped on the Jets bandwagon, I have a few questions that need some answering if anybody can help that would be great, first of all going to tell you what I'm running in is a promixBX/perlite/Vermiculite mixture amended with some dolomite lime
My question is is the dolomite lime enough calcium and magnesium to go full cycle or do I still need to use Jacks calcium nitrate along with the citrus feed?
Also do I use the citrus feet full cycle or do I use jacks 20 20 20 in veg and then flip over to the citrus in flowering?
I also have the jacks blossom booster should I use that at all? or just stick with the citrus feed all the way through?
Any help would be great guys and sorry in advance if this question has already been answered directly or indirectly

Cool, I'm on 1st grow using it and I didn't start using it till week 5 from seed. Still feeling my way through... running 10 plants, 7 different strains...3 of them have a little burn, others perfect...and ALL the buds sure look nice. It's some obviously powerful stuff...
Can't wait to start next grow using Jack's from start to finish...less is definitely more, Lol...
