Hi
@FelipeBlu and thank you very much for your input!
I’ll try to explain and answear as detailed as I can, so you could get the better picture whatsupp.
1. What is the N% in the BioBizz CalMag? And the Ca and Mg percentages too.
2. Does the Mineral Magic silica have any K?
1. I’m using Bio’s Cal/Mag because it only contains Calcium and Magnesium, no Nitrogen at all. (Thats at least what I read and label either doesn’t mention anything about N) Ca & Mg-% are: CaO:4.2% MgO: 1.7%
2.
T.A’s Silicate doesn’t contain any K. Label says: 84% Silicates (Carbonates 16%), Iron(Fe): 2.4%, Magnesium: 1.8% and Sulfur(S): 0.15%
Without that information, the NPK is already 56-7-30. If the silica doesn’t contain K, it would appear that there isn’t enough in your mix. And if the CalMag has any N, that’s going to throw off the N:K ratio even more. This ratio is pretty important, and you should always have at least as much K as N. This could indeed be K def, even this early.
Yes NPK ratios being a bit off from the track right now (because for now Ive mostly used only Micro and grow) So the res mix contains a lot more N than K and very low amounts of P.
And GHE/Terra Aquatica TriPart-serie is known better as old name
GHE Flora-series (FloraGro, FloraBloom & FloraMicro)
GHE/T.A TriPart NPK:
FloraMicro (soft water)
: 5-0-1 and also contains Boron, Fe, Cu & Ca of low amounts
~ Res has 0.75ml/l of Micro (7.5ml total)
FloraGro 3-1-6
~ Grow dosage in res is 0.5ml/l (5ml total)
FloraBloom 0-5-4
~ Bloom dosage in res is about 0.25ml/l (~2.5ml total)
At this stage of the growth (between first roots & first leaves-mark) if following GHE TriPart Feeding chart the recommended dosage for hydro would be
1ml/l of each three. (see chart below). As mentioned above current dosages are like 1/2 or 1/3 strength from recommended. Micro is the only one which is almost running with the recommended dose. So watching NPK’s and doses from above its pretty easy to tell theres somewhat more N than K or P.
If I would mix for example 0.75ml/l (2/3 from recommended) each three of them, that would give me a more balanced ratio for N&K and a bit less P.
Or mixing up a Nitrogen & Potassium-focused mix for example
1ml/l Micro and
1.2ml/l Grow would give me a more N&K balance. Seedling looks like it has enough or maybe even a little excess Phosphorus (
dark/purple stems on first three fingers and some of the other symptoms could match as well…meh these all excess and deficiencis appears to have so much same kind of symptoms)
…But I guess this shouldn’t be the case, so excess Phosphorus can be left outside.
Then conclusions about Ca or Mg defiency: it could have been Cal/mg deficiency, which might be getting better since it doesn’t really seem to appear on newest growth. But the growth is still very slow/stunted. Stalk being very thin and she looks like she couldn’t even carry heavier leaves or produce thicker internodes.
And finally, in what order do you mix your inputs?
First I take separate 1L bowl where I place handwarm water and mix in the Silicate, then having 10L bucket where I mix up rest of them. And in this order:
1st - Cal/Mag
2nd - I pour in Silicate from separate bowl
3rd - TriPart’s (Grow,micro&bloom)
4th - at this point if theres room for 0.1 EC rise then I mix in 3ml/l Root Booster. But if EC already high then I just skip that.
5th - pH down supplement. After mixing up everything before pH down, pHs usually something between 6.4-6.8 and then lowering it down to 5.8, sometimes it drops to 5.7 or even 5.6 but not adding pH up, because at this low EC level the pH will eventually slowly rise.
..In my understanding this is the order I should mix them. Idk if it matters if I first mix in Silicate or always Cal/Mag first.
Then the heat/light stress. I would say it had heat stress for sure and most symptoms on foliage refers to it. But the environment temps are nearly perfect now, so that shouldn’t be a problem anymore.
So then final conclusion:
A) Cal/Mag deficiency(?) - But most of my nutes includes Calcium (silicate, micro and then Cal/Mag so should have plenty of Ca & Mg sources)
B) Potassium deficiency(?) - this is the most reasonable that I came up with. See picture below and most of the symptoms refers for the lack of Potassium.
~ yellow color from the tips, brown spots, edges turning into brown/crispy/burnt
~
Weakening of the plant
~
slowing down development
Also pH being adjusted twice per day to 5.7 or 5.8 (in ~12hrs it usually climbs up to 6.0-6.3) So in that range NPK’s and micros (Ca/Mg/Fe/Cu etc.) should be absorbed.
Compared to the root mass plant being way too small.. theres punch of happy white roots comming thru the net cup and longest ones are like 6-7inches. If I would only look at the root mass I would guess the plants age between 2-3 weeks.
What would u suggest me to do? 
Should I slowly start upping the nutes or just make a new patch (following the char) or just mix up Micro & Grow to get balanced N&K ratio?
As you mentioned before that N and K needs be in balance, we can take another example: Critical 2.0 in
coco Ive been misting it with Root Booster and Micro so the coco one doesn’t either have N & K in balance.. It only has N availabe pretty much. And her serrated leaves starting to show same kind of symptons (leaves starting to yellow and edges getting brown)
E: and update how she looks today.
Serrated leaves are completely lost, but thats not a big deal. See those leaves as well (IMO theres more Ca deficiency shown) and then first three fingers…Their tips/edges also got even worse. And comparing those leaves to the Potassium deficiency, I only found it match-match.
Newest growth looks somewhat healthy, except that brownish newest tip, but it might turn into green as the first actual developing leaves did.
Still kinda ruff look and leaves curling down a bit.
E2: Also during the night EC had dropped 0.1, pH had risen from 5.8 to 6.1 water level pretty much still static, hard to say. But I guess thats good at this point(?) older age if it would stayed static water, pH risen and EC dropped then I’ve should lower EC.
Because after moved them inside the tent they’ve had almost a perfect environments:
