Hello everyone!
Grusonii 7months, this problem apearred after i start to water them above (till now i watered them from the bottom). Could this be the reason of rotting(if i understood right) ?
P.S. They are under artificial Light.
Thank you!!!

And now how do your seedlings look? Îs everything ok ?

unfortunatelly,i can't add any photo...it says it is too big...after i resized it,the same mistake...

Do you think it was rotten?
