Uhh, i just started these seeds in my new home made bubble ponics system... the three seeds sprouted fine. they were all doing well untill, i woke up this morning and one is GOING DOWN. but the other two are fine. here is a picture tell me whats wrong.
It looks like the tap root sprouted close to the surface. Me personally I would start another cube in ph'd water, take that one out and place it in a new cube. You might have to possibly use something to make the hole deeper in the new cube. Just be careful when you tear that cube apart. Good luck.
Hey, when it starts making roots off of the taproot they don't start out thick... LOL. If you hurt/killed any of the tiny roots it might be stunted in growth... look into givin it some Superthrive if you find that it's growth falls behind it's siblings.
If you have this problem again just dip the root into some cloning gel and then just plant it back down a bit deeper.
As well as helping it to root most rooting gels have an ingredient that helps to stop any rot
It looks like it may yet die to me but hope for the best huh.
You could always give it an extra chance by carefully parting some of the rockwool from the stem and dipping a cotton bud into the rooting gel and letting the gel trickle down the root.
