An ideas whats going on with my plant?

Hi fellas,

This is my first attempt at growing and really getting excited. I planted 5 nirvana
Bubblelicious autoflower seeds 10 days ago, 4 sprouted and were looking good. But in the last 24 hrs or so one has started looking ill. They are all in the same cloner with a ph of 5.8 and very little nutes. The other 3 look great so I don't think it is the water or nutes.

I originally thought that it wasn't getting water until I lifted it up and saw the long ass root. So now I am at a loss.

Any help would be great!

For a reference here are the other 3 that sprouted.

hmm 40 views and no ideas?

Try watering the medium by hand. Mayb most of the roots are still in the cube. Is the cube dry?

Ya cube was dry. But you can see it has a long ass root going down. I sprayed it with ph'd water just the same thinking the same think you are... it looks under watered.

Fuck its getting worse with spraying.

it's dieing fast. anyone have any ideas before i lose her?

Damn that's the only thing I can think of man. Mayb the taproot was damaged. Those young roots can't handle much of anything. Best I can do for u is reply to give ur thread a bump. Good luck bro.

Thanks for taking a look man. Checked on it this morning and its even worse with the spraying last night. I guess I'll just caulk this one up to a loss.
