How much fertilizer, Lucas formula with Dry Kool bloom, before harvest?

How much dry Kool bloom should I run with my last shot of fertilizer? Or should I just use Dry Kool Bloom alone?

I have been running the Lucas Formula and using 2.5ml of liquid Kool bloom outdoors in the ground.

We are having amazing weather and I will water 2 or 3 more times.

Next watering I think I will run 4ml of Micro, 8ml of Bloom and 1/4 teaspoon of dry Kool Bloom per gallon.

Should I adjust anything?

The coloring on the large water leafs is she hungry, deficient, or due to age and season? She is about the closest to finishing. That rust color is showing on only 1 plant and all have been fed the same.

When running Lucas you need no bloom booster. Just decrease the micro and increase the bloom. That changes your npk without buying anything else.

I have always run a 1-2 ratio with the liquid kool bloom in flower. Shit, I put it on my tomato plants, flowers ect and they love it.

But I have never run the dry Kool Bloom. I know I need to be careful with it because it can burn, but everything I am reading as a finishing product, it works well when you use the right amount at the right time just before you finish.

So should I run it with a tuned down Lucas, full strength Lucas, or just by itself for the last kick of fertilizer

I’m not sure about dosage in soil, I grow hydro.

But I do know that the pk, mg, and s found in gh flora bloom, and Florapro bloom powder are the same pk, mg, and s that’s in all bloom boosters. Why buy more than 2 product when they already contain what’s in the products you plan on buying?

More than 2, because all are derived from different things and will have different uptake rates. Chelations.
General hydro bloom, kool bloom liquid, and dry kool bloom are made differently.


The idea with dry Kool Bloom with the high levels of P-K it shocks the plant at the end to produce a bit more of everything while helping ripening.

Advice from anyone who has run it in soil outdoors please.

Monopotassiumphosphate, potassium sulfate, and magnesium sulfate don’t need any chelation agents to be available to a plant. Nor do they require the mycorrhiza in the soil for plant uptake.

Just because you have a hammer...

Skip it and enjoy cleaner and more enjoyable flowers. I eventually threw that stuff out.

At 1-2 weeks left you should be plain water only.


I am glad I am not the only one who thinks that

I mean, how many total plants are there?…6 ,10?

with a harvest in two weeks , how much more weight would he get , another ounce per plant?…

with good soil , some years all I did was add a little worm poop tea a few times

but mostly just water water water

15 years growing in this same spot

twice a year I would clean out the henhouse that had 20-30 chickens roosting in there and 6” inches of wheat straw hay on the floor

all that hay and chicken manure got tilled into the garden twice a year for the last 15 years

one chicken produces approximately 1/4 pound of chicken manure a day

multiply that by 30 chickens and that’s a lot of manure

occasionally I would throw in some bat guano , blood meal , and worm poop

with all that being said , I had the option of just plain water all season , if I so chose

In conclusion , I vote water until the end. 🤓🤓🤓

I’m definitely not an expert in soil growing. My friends that are organic soil growers tell me that using any salt nutes can harm the fungus and bacteria that enable the plant to uptake organic nutrients.

hey there Hank , what did you decide to do?…🤓
Thanks for asking. Two plants look like they're going to finish up sooner than the others. I'm going to try a little experiment and run a light Lucas mix with the dry Kool Bloom and the other nothing.
I didn't run into any deficiencies throughout the whole grow so I know the plan still have energy stored up....
My other plans are leaning a little more sativa so they look like they have a solid 2-3 weeks. i'll fertilize them one more time and let it be.

I was hoping whatever you decided to do, that you would follow up and show us. Too many forum posts leave you hanging. It’s so nice when the topic comes to a conclusion.

Good experiment , I was gonna suggest that

Obviously you can use the results as knowledge for future hrows

Here is to a happy harvest!

personal stash grow?

when I look back at my indoor feeding charts for lucas formula with koolbloom liquid and powder I can offer the following "advice".
assuming a strain needing 10weeks of 12/12 flowering time you apply liquid koolbloom in weeks 3,4,5,6 and then begin blending it in week 5 with powder KB
the actual break down goes like this
wk 3 @ 3mls liquid KB per gallon
wk 4 @ 4mls per gallon
wk 5 @ 5mls per gallon + 1ml per gallon Powder KB
wk 6 @ 1mls per gallon Liquid KB + 2ml per gallon Powder KB
wk 7 @ 5mls Powder KB
wk 8 @ 5mls Powder KB
wk 9 @ 13mls Powder KB
wk 10 flush/water only

Now bear in mind this runs with a modified lucas formula that is also graduated as the flowering cycles progresses. It is apparently the method of application Swerve used for his OG kush recipe. FWIW.

I hit these 2 plants, military chocolate, and beaver cookies with 4ml of micro and 8ml of bloom and1.25ml of dry Kool Bloom.
So I have not seen any new growth on 1 plant and 1 plant seems to like it and spitting out a few new pistols.
These 2 plants look close to finishing both in terms of pistils and trichomes. Almost all cloudy and a rare amber here and there.
Overnight temperatures have dropped a few times to about 39F and other times in the mid 40's.
Day terms have been very nice high 70's and low 80's.


For my other 4 plants, I hit with the normal 8/16ml and about 2.5ml of liquid Kool bloom.

The other 4 plants need 1 or 2 more weeks. I did give everything plain water today



I think in a few days I might hit the others with a light dose of the Lucus formula and dry Kool Bloom.

In other words, the jury is still out if it does much of anything...
