Hi guys,

I've just started my first indoor grow and I already struggle. My seedling is turning yellow and I don't know why.
This is what I have done:

1 - Soak cube in 5,5ph clear water for 24h
2 - Soak cube in extremely light nutrient solution for half day
3 - Plant seed in cube under the dome in the heated greenhouse 30c°
4 - Seed sprout on 4th day and grow 1cm per day for 4 days
5 - Stop at 6cm and start become wider on day 8
6 - 1st pair of leaves growing ok for 4 days
7 - On the 12th day cotyledons turn suddenly yellow and tip of leaves as well

I'm using led lights, white and blue, 40cm above cube. I keep cube wet but not soaked.
I've attached a picture to help your analysis.

Anyone can help me ?

you going hydro or soil? hydro i never done but if its soil you should have put it in medium already. also led i think you should have further away atleast what i read other say.

on what i see i think you need to adjust light and look over your water skills, from what i know and experince. Also let pleople know if you do hydro or soil big diffrent it is, also more experince people might know right away whats wrong. other then that i can only wish you good luck and for whats it worth i use this page to figure out whats wrong:
this might help ya.
