Nutrients for flowering

[Philweb4321]

Hi I’m just wondering if anyone can suggest a fertilizer to use for outdoor flowering stage. Preferably something that isn’t going to cost over 100 bucks or anything like that I used miracle grow bloom booster last year I think it was 15-30-15 would that be ok to use at about 1/3 of what it calls for? Thanks

I'd start with 50-50 blend of these.
One gram or ml per gallon total each watering.
I only water near the rootball, where the nutrients have been depleted, as my mix is decent.

After a few weeks transition to only using the
Bloom.
Doesn't sound like much but it should be enough at the start. Adjust as needed.

Was it ok last year? If it didnt get wet its fine. If your not organic or just didnt like it, Jack's . I heard all blue powder fert is samething. Rebranded

That’s great thanks for the info

If you are going with chemical nutes over organic, second the recommendation on Jacks. Jacks has done quite a bit of cannabis specific research and development for their products. Many growers using chemical nutes swear by Jacks. Jacks stuff is also slightly less hated on here than MiracleGro stuff

Check out the Episode 74 of the Cannabis Cultivation and Science podcast hosted by Tad Hussey - he interviews Dr Cari Peters who is a chemist JM Peters (company that makes Jacks). The host normally focuses on organic cultivation but this was an interesting episode on chemical fertilizers.

Right on thanks for the info

I'm also in need of a bloom fertilizer recommendation.

Would like something organic, not chemical.

I hear Jack's has heavy metals.

Dry? What are you using now

Im using the hesi pack fertilizer for outdoor and doing amazing job she start smelling like crazy after put bloom complex for first time..

 

[Oldgoat1959]

At flower I'm putting 20 grams per gallon of the seabird guano with 8grams of the bat guano.
Stir occasionally for two days then add 4 grams per gallon potash.

Diluted to 1/8 strength for starters.

 

[crisnpropa]

Is there any recommendations for liquid organic?

 

[Oldgoat1959]

I used to use Biolink 0-5-5 from Peaceful Valley.
It's just mined Rock phosphate and mined Potash dissolved and bottled.
Same as above without the bat guano which is giving a little nitrogen for the next few weeks.
Fed them yesterday and leaves are standing straight up today.

 

[Oldgoat1959]

They liked the feeding. I went with 454 g of the diamond k. Added it at the end, after the two days of stirring the 2290 g seabird and 1000 g of bat guano.
Diluted 50% more than usual to 180 gallons

Any of the major one or two part dry nutrients-Megacrop, Maxibloom, or Jacks. I'd just get a little bag of a one part that has the calcium/mag in there. If organic, any tomato food like Dr. Earth or Tomatotone. OR, just get a jug of Neptune's Harvest-killer results and sticky terpene bombs.

For calcium/magnesium I just pulverize dolomite lime and water it in: it’s stupid cheap and there’s your calcium and magnesium. Works amazingly well for me.

Yep. Maybe a pinch of epsom salts if you specifically see Mg deficiency - but if I use enough DL at start, and watch pH, I never have these 2 issues (cal/mag). YMMV IMO

 

[sirtalis]

For mid-flowering, I've started working with gypsum, langbeinite, and guano.

Gypsum for Ca and S
Langbeinite for K, Mg and S
Guano for P
A tiny dash of BAS Big 6 for micros

 

[Warfox]

Yep. Maybe a pinch of epsom salts if you specifically see Mg deficiency - but if I use enough DL at start, and watch pH, I never have these 2 issues (cal/mag). YMMV IMO

AND if you use enough dolomite lime in the beginning, it will pretty much buffer any potential pH problems during your grow.

 

[crisnpropa]

Is this stuff any good for P and K ?
