I took three of three species and put them is reservoirs filled with a maxsea solution up to 4 different ppm. The control of ro water, 200, 400, and 600. The sets of pictures are less than a month apart which is kinda crazy to me. Also, the plants were sown on new years and all have flowered but the madagascariensis.
The ro did not grow at all despite an okay root system. Ended up losing or nearly loosing several in the ro group as there was litterally nothing for it to eat. No spring tails made it in.
The 600ppm have growth and flowered but have horrible root systems. They are surviving but poorly.
The other two are entirely viable with 400 being the obvious winner in growth and flowers but notibly greener. Another good example of nitrate limitations leading to pigmentation.
They receive the same light of 700ppfd for 14 hours a day and concentrations are maintained within about 50ppm of lable.
Doubt I'll ever actually use this information but here it is for anyone to see i guess.

More data equals more accuracy. So for example if you have five in the control group and five each of the others, that can help eliminate random variables like the result being messed up by rot or an individual difference in the plant or something random like that.
Well shit…super helpful test… what is the soil mix peat and perlite? I always wondered what they need without natural food..
I have started fertilizing my north American plants with 200ppm Better Gro Orchid fertilizer and I have wondered how far I can push it. I put the solution in the pitchers and foliar feed my drosera.
That has been my experience too… no nutes or prey means extremely slowed or no growth. Afaik all plants need the same essential elements, but with various concentrations, ratios and/or tolerances.
MaxSea isn’t a complete fertilizer since it’s missing calcium and magnesium, plus it has 3 kinds of nitrogen, so I wonder if you’d have different results with another fertilizer. What do you mean by nitrate limitations leading to pigmentation exactly?
So their reservoir water always had those ppm, like did you dump and add fresh at the 200/400ppm again when it got low?
Also this would probably explain why mine grow so dang slow lol
