Plant slightly yellowing

[Lzcalm]

This is my first indoor grow so i'm a noob, I've grown outside once. Why are they doing this? Picture was taken just before I watered them. I'm using soil, 600w hps light.




The other plants i'm growing are a normal green colour but this is the only one that's yellowing.

Any help much appreciated.

Thanks!

Ive only been growing for two months and my seedlings were not that colour. Are you adding nutrients? I did not add any until around week 4 from seed. I still check my ph in my soil, what is yours? Also how close is your light? Im still learning myself, but I have learned alot in 8 weeks! Still plenty more experience to come im sure.

What soil are you using mate & is that plant the same strain as your others?

[Lzcalm]

Same strain as others, i'm using john innes 3 :P

Most strange...

I was thinking maybe had to close to light because i'm doing 24/0 atm because it's cold although if it was the other two should be same colour :/

Haven't gave them anymore nutrients other than whats in soil. I normally give them a mug or two of watering about once a day ish, normally when the soil feels dry.

Haven't ph'd water because i'm very lazy and need one of those ph things. The soil on the bag said 6-7 PH i think. I use tap water that's 1 or 2 days old because i fill up 2 watering cans and leave it.

Time to add some nutes

looks to me as though the rh is too low,put a cut/half bottle over her(breathe into it before placing )thatll then provide a nicer rh atmosphere for her and she should perk up.
its a lift it,breathe into it n replace twice a day sort of thing till she perks up/gets stronger,then play a very light breeze over/past her,thatll also help strengthen her up,a veeeery light breeze mind ,dont want to go battering her with wind.

keep the 600w up high,thats a lot of light for one so young.
