Hydroponics/Double Net Pot Plants/Seedling is purple 💜

Hey there,the problem with placing 2 plants in 1 rockwool block is that both plants have different genetics,even if you popt 2 beans of the same strain in 1 block you will run into problems with one or both plants because they are completely different plants so they will react different to every thing you do with your plants,especially when feeding,one will need more food than the other so you always run in to the problem of overfeeding (the dark green one) or under feeding one the only way I see how this could work is when you work with clones because clones have identical dna so they react the same, This is also the reason why commercial growers use clones, you can feed them all the same nutrients and they will grow and flower almost identical so you get a lot of consistency in all your plants

Most likely the greener one will outshine as it will be better at photosynthesizing. Kill one off so the other can live a better life. or try and transplant it. Your Call.

no.. that doesn't look okay, lol. they will definitely compete and most likely 1 will dominate more often than equal sharing. even the non-dark seedling is looking rough. Definitely some sort of imbalance in your water. If it's too cold at night, might be why the one turned oddly dark and maybe other is abit more resiient in that 1 way but you already have visible symptoms in leaves... something is drastically off for that to happen this soon.

NEVER grow 2 plants side by side.......they will compete for EVERYTHING and instead of getting 2 full plants, you get 2 one quarter sized plants.
