The point is, prawns love shit! We eat it for breakfast! And we have a hard shell . . . :wink:

Er, I'm not sure where I'm going with this . . . except, perhaps, to say sometimes a good old trollfest can also be a good old laugh and turn up some real gems in terms of sharing knowledge - so none of us should really get too upset what happens on the internet. It's all a bunch of pixels, after all.

Hmm, I think PsychoPrawn could be appropriate.

Right, so its an absolute minefield out there when it comes to nutrients for Coco, every single company has wildly differing NPK ratios just for veg (some have insanely high k levels to boot). Considering what we have learned under LEDS what would an ideal ratio be?

I really wanted to leave this topic till a bit later but anyway I am all ears, tell me your thoughts, previous experiences and what you think would be ideal. I want to get back to the KISS method so Prawn you know I like your concept enlighten me pls.

Keen to hear others thoughts also and I wish Tbone and Soil2coco were here for their thoughts!

Just get yourself a couple of bottles of Canna Coco A+B and follow the directions.

Use a silica additive.

Let your pH float.

Add CalMag only if and when needed (in my experience, you may need it under LED, but you don't need as much in summer due to high transpiration and the fact rain flows fall off and scheme water gets iuncreasingly harder as it draws from groundwater sources high in calcium, magnesium and other salts, which also raises pH) .

Resist the temptation to add shit unless you know exactly what you're adding!

Listen to your plants - they will tell you what they need - and don't listen to anyone else. :P

Heheh! Would you believe all those avatars I posted each belonged to a separate account I used to log into at Overgrow? In those days, you didn't need a proper email address - you could register as many sock puppet accounts as you liked to have some fun.

But I only used them in the Shark Tank, never in the grow forums.

The ratio is far less important like you may think. Important is that all the nutes are available and that there is no deficient or toxic level. Especially in a hydro setup the plant take what they need. So the most important thing is the level has to be in the sufficient range. But with a non optimized formula you would waste nutrients cuz there are more unused elements left in the drain. So an optimal formula is still useful..

Would you believe when I say this 3 plants below gets an NPK 3-27-18 bloom fertilizer, 75ppm calmag(my tap water has only 0,14mS/70ppm) and a bit kelp extract? 600ppm currently and I set the water to 5,6 because an half hour later it stabilize at 5,8. Within 2 days the PH of the solution drifts to 6,2 or 6,3 and its time to mix up a new one for another 2 or 3 days.

Thanks to TheDawg we have to add "smallpenis" to the party cup competition updates this week, lol! That's not my idea!

I believe it. And I subscribe to the same theory that plants take what they need. I use a flowering nutrient all the way through my cycle, too.

The problems with unbalanced NPK ratios begin when you increase pot size and don't flush out the excess nutrient properly. Or in a recirculating system where the unused salts start to build up and exacerbate the imbalance.

Again, there is no "one size fits all" grow advice - you need to tailor it to your own circumstance and style. But we all have to begin somewhere . . .

Well no, but that wasn't the issue here.

Agreed. Growing is a holistic venture.

Certainly. If we are speaking hypothetically.

But if you have been growing in coco for many years and spot a common problem that you know - from experience - can be treated in a straight-forward manner, wouldn't you tackle it as such?

From where I sit, I saw it the other way around!

To me, the problem seemed obvious. To others, perhaps not.

In no way was I discrediting what Randomblame was saying. But at the same time, I felt that while one conversation was going on about VPD, the obvious issue of nutrient management was not being addressed.

So that's the approach I took.

@Randomblame can correct me if I am wrong, but I'm sure that's the way he saw me approach the issue, too. There was absolutely no conflict with what was being discussed. Just a general difference in views on what should be addressed first.

I appreciate the comment. The LED community has given me a lot - and continues to. So if I can return the favour by sharing a bit of general grow knowledge and experience, then I hope that makes up for my relative inexperience in other areas (specifically growing under LEDs).

Of course, by now you've realised I don't mind a bit of robust debate - as clearly you do, too - so we can all still have a virtual beer and laugh about things once everything has been resolved. Or even if it hasn't.

It's how we evolve.

BTW, dissected quote arguments are the worst, aren't they? I saved that one for you, my baseball tragic friend. You know I don't waste my time arguing with any old bludger! :P
jaysus you aussies are wordy!

Luv it tho.

Got a bone to pick with you sometime about ‘indoor growing is about mimicking the sun/nature”...or some such nonsense...

good to see it looks like your issues are behind now, and i kind of agree with the diagnosis here i think you were just to hot on the nutes causing calcium lockout ect then there was the snowball effect of vpd out of range which just compounded the original problem.

i will say i have a fair amount of experience with canna in coco and cannas calmag is strong. 1ml litre is full strength, at 0.2ml a liter it will add approx 0.1 to your ec so at 1ml a litre it could be as much as 0.5ec added to your total ec.
canna coco a+b at 2ml litre will be approx 0.8ec (if its the same as canna cogr which i belive it is as both are 4ml a litre full strength) in pure water, add the 0.5ec from the calmag then i think you said the background ec of your water was already 0.7ec and you are getting up there at 2.0ec.
(i rarely go over 1.4ec in full bloom but my water is really clean with a background around 0.1ec).
cannzyme and rhizotonic wont effect your ec.

have you thought of using canna cogr?, i have never used normal canna coco a+b only canna cogr. cogr is cannas expert coco feed it comes in a separate a+b tailored for veg and flower. it was designed for their cogr slab system (compressed dry coco brick, looks like a grodan rockwool slab) but i have only ever used it in normal coco in pots.

i have never used cogr under led (yet) but under sodium i never had any problems just runs like clockwork with amazing results.

actually thats a lie lol, i forgot i am using cogr vega under led for vegging at the minute no problems so far just haven't flowered with it yet.

When you think you know better than Mother Nature, you don't. So I don't pretend to. She's been at it a lot longer.

Did I tell you prawns love picking bones? It's our second favourite thing to eat after shit. :mrgreen:

the mother nature thing is a hard one, in one way WE are mother nature we are not separate from the universe we are the universe, so every time you grow a plant mother nature is at work.

then you could argue our sun/any sun wasn't designed to grow plants(well it wasn't designed at all just a consequence of what we call the laws of physics) and that life/plants have just adapted/evolved to make best use of it.
could it be improved...? maybe...i dont know, but i dont think anyone on this planet is qualified to say its impossible.

we might have the shitest sun in universe for growing bud, aliens might have been watching us for years laughing their arse off at our poor crops lol.

I missed this last night . . .

I guess first thing's first: you could point to the quest to create an indoor light that most mimics the sun as just one area where we aspire to replicate Mother Nature. It's the reason why full spectrum LED has - for the most part - replaced blurple; why the Emerson Effect is being explored; why UV is being supplemented; why CMH is fast becoming the preferred indoor HID; and why plasma could potentially be the next Big Thing.

So the lights are artificial, but the brief is to make them more "natural" or "sunlike".

Same goes for growing media. Hydroponics may technically be artificial, but the trend is to make it more organic, which is why - even in water culture - growers are switching from sterile recirculating systems (using minerals salt nutrients and chlorine and H2O2 to kill everything), to organic-based nutrients and/or supplements in a bid to colonise beneficial bacteria in the root zone, and reduce or eliminate the use of pesticides and other nasty chemicals to improve yields and quality of consumables.

Most of the progress in indoor growing in recent times has been trending towards these organic-based solutions (I don't mean "certified organic", but rather organic in the broad sense).

Climate control is another area. Airflow, humidity and temperature regulation are all based on how our plants have evolved and respond best under natural conditions.

Of course, I also tend to agree with @grotbags that we - humans - are also part of the ecosystem, and that anything we create is de-facto "Mother Nature". There is certainly a philosophical argument that we shape evolution and that the world around us thrives or dies in response to how well it fits in with our own activities.

But this is also what I like to refer to as the "Butter vs Margarine" argument: one is mostly natural and tastes great, the other tastes like shit and probably gives you cancer (I'm only half-joking).

We already have butter, so why the fuck would anyone invent margarine? More to the point, why the fuck would anyone eat the shit?

Well, because humans - in their infinite wisdom - decided the only way to get people to eat shitty margarine was to demonise butter! Tell them it's full of harmful, mono-saturated fats etc that will give them a heart attack. Problem is, margarine was full of even worse trans-fats that killed them quicker!

Hemp suffered the same fate when the DuPont Company invented nylon. We all know how that has worked out (plastics have fucked the world).

The motto is, humans have been trying to replicate nature since we evolved. And for the longest time we have been arrogant enough to believe we know better than a process that has been going on for, if not 4 billion years, then 15 billion years or even longer (if you believe the multi-verse, or recycled universe theories).

Everything we create is a reflection of the world around us. Yet almost none of it stands up to the very best of Mother Nature. A spider's web is stronger than steel and stickier than glue. An eagle's eye is sharper and more compact than any lens. A human brain is more efficient than any computer.

You get the idea.

Maybe one day we will get there. But until then, the gold standard is - and perhaps always will be - Mother Nature.

I hear you, but i’m not trying to create nature in my tents, no matter how you might interpret what i’m doing.

If someone wants to use the argument that the pieces came from nature: so what?

I don’t buy the argument that because the bits of technology i’m using originated in nature, that makes what i’m doing natural.

It’s not.
