Picture having to take a six-beer piss in the middle of the night and the fuckin' zipper is stuck to the tent you're sleeping in.....really stuck....and you cannot get out.

I had to cut the door open......and it was a brand-new tent.....which went into the dumpster the next day.

You gotta order the tent with the piss drunk fly...

Or maybe the new Levi's 501 button fly tent. They're small tho, for a snug fit...

I think I have some anecdotal supporting evidence; on a fresh batch of nutes, my ladies go through them rapidly. After a few topups, the EC quits changing much, but the plants still seem hungry. What you're suggesting about potassium could have a lot to do with what I'm seeing.

In my data, I saw that N was the most used element which was followed by potassium. I would bet the farm that your initial EC drop is your plants taking up N along with the other elements in a particular balance. If your res becomes 'out of balance' from topups, feedings tend to slow down. I've noticed this in my own garden when I've tried to feed my plants what I want them to eat rather than feeding them what they want to eat. This is why I said earlier to what's his face 'just because you're feeding more of a particular element doesn't mean your plants are using it'.

I've been growing with Jacks for almost 2 years and cannot think of a reason to ever consider another manufacturer.

I've played with different NPK's and for me I like the Bloom Booster (10-30-20) from beginning to end. I too use Happy Frog as I find it stable and consistent.

I know a lot of growers that prefer the lower P of Orchid FeEd, but for me I found my bud growth suffered when I ran it. The 20-20-20 certainly is a safe bet too.

I DO have to read my plants and some need extra cal/mag, and other's require an occasional dose of bat guano.

I know this is an old thread but Ide like to see if I could get some insight from some of you more experienced farmers. I'm on my third grow from seed now and using Fox farm ocean forest, earth juice calmag, and jacks blossom booster through flowering. With each one of my grows I've had pH problems with the soil. Runoff always seems to drop down to around the low 5 range. Before starting my current grow I decided Ide mix dolomite lime in with my soil (about 4 tbsp per gallon of soil) because from what I understood the lime would help regulate the ph of the soil while also providing some micro nutes. Problem solved, or so I thought.

I use rainwater, but always pH the water to the range of 6.2-6.8 after adding my nutes. Should I try using Happy Frog next time? I really like the Jacks products and am wondering if my problem is the Ocean Forest soil. My last grow turned out great despite having to flush the plant like every other week to fix the pH. I got 4.5 oz off the one girl.
 
Ph in soil is less of an issue than with hydro as soil buffers PH pretty well. I use water straight from the tap (last time I checked it was around 8.1) and not had any issues. Jacks, and I suspect similar nutrients also lower the PH.

The thing I ask myself about PH is "Does my lawn, my flower garden, my bushes, and my trees need to have their PH adjusted?" The green grass, my beautiful flower garden, and my healthy bushes say "no".

That's the beauty of soil growing as we're giving the plants the medium God intended to have things grow in.

Now in regards to Ocean Forest.....I think you can do better with Happy Frog....it's cheaper, not as "hot" as Ocean Forest, and I continue to use it 3 years into growing without issues. There may be better and/or less expensive potting soils out there, but since I've had good luck with Happy Frog why change to something else?

Thanks for the insight bud. When u put it into the context of "how God intended plants to grow" you hit the nail on the head for me. I'll try out the happy frog next go around. Thanks again

Let's hope this thread is big enough for those using similar dry nutes from other manufacturers, like Hydrogardens.com in Colorado Springs, CO.

Their product really isn't enough different from Jacks to, well, make much if any difference. I got their stuff because it was physically close to me, and I'm happy with them. I was unhappy with the nasty blue dye, too- I thought it was covering up stuff that wasn't going into solution- or just sand. I understand they don't use it anymore, so that's good.

On with the thread! Share nute ratios, anyone? Here's mine:

All measurements are grams per gallon;

VEG
2.5 of the 5-11-26 mix (micros are in here too)
2.0 calcium nitrate
1.5 Epsom salt
EC 1.1-1.4, pH 5.5-5.8

BLOOM
2.5 mix
2.5 cal ni
1.5 Epsom salt
.25 MKP
EC 1.3-1.6, pH 5.8-6.2.5

This in RDWC, climate is 80f, 60% RH. Sometimes sealed and bottle feed CO², other times vented.

I have really been thinking about switching to this. For $105 you can get 25 lbs of the two part and a 5lb bag of epsom salts and at 2.5 gs a gal send like it would last forever. I have seen the results of it for my self. Do you add anything else to that. That ratio send like it would work great in coco too wroth is what i use. i feed in that ec rang ever time i water usally 650-700 5.8 ph with house and garden. The ph comes out in that rang without correction?

For me, pH usually comes out about 6.1 but is easily corrected. It works fine in coco, too.

The cost thing is a real eye opener, isn't it?

Fuck yeah man I'm going to pick some up tomorrow and use it on a couple of my girls this round. I got some 2 weeks into veg so ill be able to compare. If itgoes theway ihope I'll be switching over and saving a bunch of money. Does it dissolve well?

Dissolves fine! But it's meant to mix into a stock solution before use; that is, don't just scoop out what you need for each feeding, mix the whole container into a stock solution and then use that. In other words, you'll make your own 'water bottle'.

If your plan is only to mix enough for a few gallons at a time, then you'll be better off with a tub of Jacks 20-20-20 or their citrus blend. @RM3 has been using those formulas for years with impressive results.
 
I agree.....my nute budget for 16 mature plants and over 20 in veg is around $10 a month.

Jacks 20-20-20 is the Swiss-Army knife of this brand's nutrients.....and those that use it rarely have micro-nute issues and have healthy plants from beginning to end. What else can you ask of your nutrients?

I did find that the 20-20-20 and the Citrus-Feed mixed better with warm vs. cold tap water. The bloom booster I use mixes well in cold or warm.

I landed on Jacks Bloom Booster all by mistake. Very early in my grow experience my mentor told me to go out and buy some Jacks......well, I didn't even know there were different Jack's products and bought the Bloom Booster. Six months later I'm enjoying 5-6 ounce plants and it was then my mentor realized I wasn't using the 20-20-20 he was recommending.....well, I couldn't argue with what I was experiencing and still use the bloom booster from beginning to end.

I've tried Citrus Feed and the general nutes from Jacks....and for some reason my plant's start bud-stinking like crazy using those nutrients. No-one else has had the same experience so I'm guessing it's the combination of Happy Frog and the variations in these nutes that is causing this...and it's probably the combination of Bloom Booster and Happy Frog that has given me some very nice plants.

I don't know if I mentioned it before, but with Bloom Booster I do occasionally add bat guano and more often I toss in calmag as this blend is lacking a bit in both. Much has to do with what strains I have going at the time. I've not used Epson but understand it's a great way of keeping calcium levels up.
 
Generic monopotassium phosphate is going to be even cheaper than jacks blossom booster. You can get 5 pounds of it for 15-20 bucks. https://www.cropking.com/catalog/nutrients-nutrients-and-additives/mono-potassium-phosphate

Epsom salt is magnesium sulfate, and thus not a way of boosting calcium. If you're in happy frog, you should be getting all calcium from the medium (limestone or bonemeal). Calcium nitrate (main ingredient in cal-mag+ and GH flora micro) is the way to get soluble calcium if you're growing without soil.

Adding epsom salt when you don't have a magnesium deficiency will actually work to antagonize calcium. (they're both cations with a charge of +2)

No calcium in epsom salt, it's magnesium sulfate in a hydrate crystal, fyi.

Interesting that you use cal-mag with Jacks. It would seem to address a potential issue with too much P in the triple twenty blend.

I love how dry nutes make my plants all frosty n stinky, too!
 
I miss-spoke......it adds magnesium...not calcium. Have I mentioned I don't use Epson salts?

Sorry for the unintended miss-information.

Online it says mix 9oz per gal for a 1:100 ratio ofr stock solution. How much of that do i use per gallon of water. I usally only mix up 20-25 gals to water my girls

I had problems mixing for 100 gallon batches, but I was getting my nutes out of a 25 lb bag, too.

so if you add magnesium you should add calcium or no? I am currently using epsom salts and gh micro/bloom. I don't wanna be fucking shit up between the mag and cal :(.

Just add what you need. If you have magnesium deficiency, just add epsom salts. Magnesium deficiency is often caused from too much calcium, so you should not need to add calcium as well. Let the plants tell you what's right.

Jacks uses Urea and Ammonia forms of nitrogen, both can combine to create ammoniacal nitrogen. The ammonia form has what is called "potential acidity" which can lower your medium pH over time. Most people don't pay attention to the different types of nitrogen fertilizers have.

The proportions are tuned to give pH in the range desired.
