Hi everyone, looks like u can burn your seedling even that u give them only water... or wtf is going on.

Yeah, first post etc etc..

But to the point, my seedling are now 16 days old since sprout, everything went fine as usual UNTIL i had to leave for 9 days, so i fully saturated my plants and leave, this is what i found.
never had problems with seedling stage, plants looks like they are over fertilized, dark nitrogen claws etc.. pots were almost bone dry, so i flushed them with ph6.2 water and run off started with ph 5.4 and it was quite dark color (my EC pen died some time ago so i can´t give readings. i only have gived them ph 6.2 balanced water 200-300ml every 2-3 days as usual since sprout.
pot size is 3.4 L.

Question is
Can they recover from this & is the cause of this dry media.
Soil is Canna terra professional.

Only 1 plant looks nice and healthy.

Yes it's a strange thing but not really once you understand what's going on. Nutrients that are present in the soil itself dissolve into the water. As the water evaporates, the solution of nutrients becomes more concentrated. Same amount of nuttrients are in the pot, but without an appropriate amount of water it's not properly diluted and becomes increasingly toxic to the plant.

Thank you Ninjadogma for good answer, thought it be the problem.
But can they recover? i have plenty of seeds and maybe toss these away and start new round... or give them a try?

It's really hard to tell. When this happens, the plant kind of does a complete stall once it reaches a certain concentration so there is little uptake going on to show you the damage that has already been done, and then when you get the water in there it resumes vascular flow and suddenly you see leaves going yellow when the excessive nutrients make its way through the plant. So what I'm saying is once watered it looks much worse, and it's just the visual effect catching up. So the outlook for recovery is really about how well it handled the situation after getting watered.
