Any current kristalon users?

Exactly why I figure adapt or perish. They'll price rubbish weed too high and people will undercut it with higher quality on the black market

pH does come in about right for me at 1:1 kristalon/Calcinit. It's only when I start dropping the Calcinit that it starts to need more adjustment. Perhaps I'll add calcium sulfate to bring Ca back up, which was kind of the plan anyway but I don't actually think I did

Or I could always just run 1:1 right through flower see how that goes. High N I found darkens the buds, I prefer that light green fluro look that seems to come with nutrient fade

I like that look. It holds false promise though. N is a major crop steering input. If the plants are light coloured, the plant is stunting it's growth to cope. This wastes other inputs, as the plants not using them.

I don't recall your numbers, but 160-220 is a good window for N.

Yeah kinda what I figured out mostly this year . I have some fairly small (ish) plants in veg so I'm thinking I might try them on .65g/L base and .8g/L Calcinit for 172N 31P 205K 124ca. Actually will be a bit more P as I'll probably mix with masterblend clone again to drive the P up a little. Will raise base later to get more K

Will do a test batch check EC and pH. Thinking EC is gonna be up over 2 but I read in another thread some of that EC is not plant available. Maybe I'll slowly get there in increments, maybe I'll just dump it in they can sink or swim lol. In veg so not too worried if they hate me for it

My environment and lighting is not dialled enough to really push the limit..

Is that 160 - 220 N a good window start to finish? I've never kept N that high in flower before I normally start tapering off week 5 - 6, and to be honest probably never even run it as high as 160 anyway. This will be my first attempt

At .65g/L kristalon and .8g/L Calcinit I got 1.8 and pH 5.3 so I'm gonna start off with that. Forgot to calculate the potassium carbonate just kinda eyed it but I don't think it's that significant. Maybe 20 - 30ml of 100g/L stock for my 200L of res. If my head maths is right should be under 10ppm?

If I ran it the other way round - 0.8g/L kristalon and 0.65g/L Calcinit I would get numbers not too far off Bruce Bugbees. But it looks like he runs CO2 enrichment and probably an optimal environment with high intensity LEDs.. I run whatever the atmosphere provides.. no A/C, HPS and CMH so I'm fully expecting to have to scale it back

Optimisation of Nitrogen, Phosphorus, and Potassium for Soilless Production of Cannabis sativa in the Flowering Stage Using Response Surface Analysis - PMC

Following legalisation, cannabis has quickly become an important horticultural crop in Canada and increasingly so in other parts of the world. However, due to previous legal restrictions on cannabis research there are limited scientific data on the ...

.65g/L base and .8g/L Calcinit for 172N 31P 205K 124ca. Actually will be a bit more P as I'll probably mix with masterblend clone again to drive the P up a little.

I don't know what MB Clone is, but yes, P could do with addressing.
MKP could give you 30 more P, and the 37 more K that is brings to the table, isn't terrible. At the same time, I would increase the calnit 10% to get N around 190, a commonly reported sweet spot. While the extra Ca is good for your pH issue, and balancing the extra K the MKP brought along.

If I had access to this powders, I would have a go myself. I'm basically there with my single bottle of Ionic, except for my K, which is 350. The link I just offered, has 3 pics that look like target practice. They claim my high K might be reducing my yield 10%. Many other studies show our plants don't actually care about K though, and this paper only has a small sample of high K plants. It could be wrong, and stands a little isolated in this view. This is notable though, using a high K feed and then a K based water hardener, as you have been.

Edit: I see the Mg in kristalon brown is listed as 4%. At 0.66g per L, you get 26ppm minimum, and I imagine it's 30ppm actual. It could do with 15ppm more. People do keep talking about it. It must be noticeable.
I also note the above linked paper tried lots of Ca levels, but never less than 130ppm.

Which Kristallon can u buy in new zealand and where from?
In Australia theyre very limited with their offerings.
I know kristalon from europe and they have the full line available. I think the only one I can buy here is the YaraTera KRISTALON SCARLET 7.5-5.2-29.9
At least i haven't found any other product yet.
If you have better options I'd like to order some from NZ soon.

At the moment I run hakaphos blue and red with calmag and mkp. But I'm running out soon and would actually like to change to Yara.

Any hint would be appreciated.
Happy Easter, greetings from oz,

Contact PGG Wrightson, they had them all except scarlet which is their "hydroponic" one. Perhaps with that I would've had less ph issues . I bought brown as I wanted low N and thats what most were using when I searched for anything about it. I think orange has less Mg? But pretty sure they told me they could get any type except scarlet

If I were you I'd get the scarlet. Better P and K values I reckon

 

[Ca++]

The scarlet has 2.5x more N then brown. At the 0.66g/L used above, that's 30ppm more N. I could work with that, and the PK is a tiny bit better. It's the Sulphur getting my attention. It's pretty high in the brown, and will be higher still with Epson. I have no benchmark for this, off the top of my head.

Edit: My tap has a lot of Ca, so the extra 30ppm, is something I can address with less calnit. I note many feeds find 100ppm Ca alright, and budbee's mix is about 80ppm. So we don't have to use that 0.8g/L calnit. However if you like lower N, the lower N brown is a step in the right direction. Later in bloom, you don't want to be reducing calnit too much to get lower N, as the lower Ca wouldn't be ideal.

Horses for courses

 

[967]

Yeah sulphur is high in brown, which I think is why I used calcium sulphate only over stretch. And makes me wonder if thats the cause of my low pH. When I've calculated ppm's in the past it's up there but not out of range of some people's recommendations. Think I remember one being 100 - 400 ppm...

I have epsom but don't really use it

Would be really cool if they just hey anyone can grow and sell it just pay some tax easy as. Won’t happen though the money boys will make sure it doesn’t. Shit thing is the countries that have gone legal it seems quality has gone down unless you grow it yourself…. Would be interesting to hear comments from the Americans about this

Some of the negatives I’ve seen with legalization mostly relate to how big money operates. Some how big growers have convinced customers that 8 week hybrids are the pinnacle of cannabis and rock hard indica dominate nugs are all that’s worth buying.

This is what I do but I'm no expert seems to work for me

50 / 50 for veg but add 15 gram of calcium sulphate to my 60 litre tank to keep calcium high in my cheap coco keep 50/50

3 weeks flower then I add 4 parts kristalon 1 part magnesium sulphate 1 part mkp and 3 parts calnit

5 weeks down to 4 parts kristalon 1 part magnesium sulphate 1 part mkp 2 parts calnit ,week 6 down to just the 3 parts kristalon 1 part calnit drop the magnesium sulphate and mkp, about 10 gram of calcium sulphate until finish maybe even dropping calnit totally by week 7 depending on how things look

my tap water is good about 60 ppm of mostly calcium carbonate

fulvic until about week 6

Just useing ph test strips and always seems pretty close



60 day strain

Just wondering if there's many others out there using yara kristalon dry nutrients?

How do you like it? Opinions on where it could be improved e.g I believe it to be too low in iron so I've been running brown 50/50 with a masterblend clone nutrient. Also my pH comes out low so I have to up it instead of down it like I'd been doing the decade or so prior. Has been suggested to me that mono ammonium phosphate might help here, but I haven't really got that far

How do people find it compared to jacks, masterblend, whatever other cheap dry shit is out there?

Ratios, EC levels, additives or whatever else people might wanna share about their grow...

Or am I one of very few using it in a country where jacks isn't available lol

The key thing for me was feeding at 2.0ec and cured any issues I had, run off in coco is up to about 4.0ec at week 4 but then looking to gradually lower it down to about 1.0ec by week 6 or 7 then down near 0.4 at finish 61 day strain no co2

It's very important for me also gradually lower light intensity and temperatures for quality ,my leds are are old type HLG (no extra red )

they can really fuck up the the buds if I don't back the off when red hairs start appearing at around day 30
