Aussie looking for 4-4-4/5-5-5 equivalent

Hi guys. I've been looking at local shops and nurseries for some decent all round organic like Gaia Green or Goguano, but after looking at a thousand organic fertilizers here, everything is devoid of P and K. Hundreds of 7-1-4, 3-1-2, 4-1-1and similar, but nothing with substantial P or K unless I go osmocote prills or salts. Our native plants are sensitive to P, so they limit it in most fertilizers. Its actually a selling point in most organics here "less than 1% phosphate for use on natives". Best I have found is 12-8-8 from Dr greenthumbs.

Mainly looking for ease of use. I have super phosphate (0-9-0-11), Potash (0-0-41-17) and microbe booster (4-1-1) here, would I be better off just messing around with these?

Use those organic fertilizers in veg. When ready to flower get anything that says it is for dahlias or roses.

Any general purpose fertilizer will work. It's cannabis and not African violets or orchids.

I'll have a squiz. I've got two rose blends here, but one is 6:1:1, and the other is 7:1:2. It seems like any organic blend has next to zero P and K. I don't even know why I'm intent on going organic anyway...just wasting time overthinking due to semi lockdown and an autoimmune condition.

I'm just being super picky. Nothing is stopping me from adding a teaspoon of potash lol. Just always on the lookout for a "one stop shop", which is probably pointless.

I was given 4 bottles of Advanced Nutrients Iguana. Organic and certified. 1 tablespoon in a gallon of water. One bottle for Grow and another for Bloom. It worked very well in Pro Mix.

The Grow is 3-1-3. You only use the one bottle until flower. Bloom is 4-3-6. Seems the reverse of what we do with a little more nitrogen in bloom than in flower. Anything close to those ratios should suffice.

i mix a 4-6-3, with a 5-3-3 and only one strain gives me problems. and the problems aren't detrimental enough for me to care about fixing the soil mix.
if you mixed the 12-8-8 with the 3-1-2 you'd get a 15-9-10 which isn't bad final ratio for cannabis in my opinion.

Roughly speaking, NPK ratios of 3:1:1 are best for any cannabis strain throughout the growth stage.

"..I have super phosphate (0-9-0-11), Potash (0-0-41-17) and microbe booster (4-1-1) here, would I be better off just messing around with these?"


you have a perfect ratio mix in there somewhere using those 3 to 4 ferts available to you in your location, working it out is the pain in the ass part.

I'd be a glutton if I purchased any more fertilizers, so Its probably best that I don't find any more anyways .

I grow one plant at a time in a 2.3x2.3 for Christ's sake so I don't know why I'm even stressing. I have 8:2:5:2, 3:1:2:1, 4:1:1:1, 6:1:1, 7:1:2, 15:0:0, 0:9:0:11, 0:0:41:17, 5:2:3:2, 11-1-13 and 13:2:11:2 here already and I'm still looking. Once you throw in the limes, rock dusts, Neem, kelp, alfalfa, barley, soybean and coconut meals you would think I could make a basic fertilizer.

Maybe I just like thinking. I've seen some killer grows where all they did was throw in 4-4-4 at the start, and top dress at flower, and I'd love to just throw a tablespoon in here and there and get magic plants.

Love stoner math. Here's the question:

You mix up

1 Tbls 12-8-8
1.5 tsp 3-1-2
1 tsp 4-1-1 Microbe Booster

What is the final NPK?

Yeah i do the same, for any endeavor in life i overthink it. Let it play out, ur mind wants to do that then do it...you'll end up same place experience takes everyone, "all i need to do is this" (reflective grin of satisfaction)

Some how I still think Im wrong,but Im not gonna google it as I know it will take hours lol.
Technically you were right. It was just rounded. I was a math tutor in college actually. It was pretty damn obvious I was a loadie, so it was extra fun helping some people. You could just tell they're like WTF, lol.

14.83333333-8.83-9.33

You stoner. There's no mixture of those three fertilizers that will yield greater than 12% nitrogen. P and K are also greater than the strongest concentration.

8.09/4.82/5.09 assuming all fertilizers have the same density.

When you quote four numbers, what are they in succession?

I was going to answer, but it was obvious to me that the weight of each would be different, so using tablespoons meant nothing too me.

A tablespoon of microbe booster weight less than the super phosphate for example. I would need each in grams before I attempt lol.
