I have 4 seedlings and this is the only one that looks like that. I'm using CFL lights and there about 1.5 inches for plant. Here is a pic of one right beside her and she looks normal.
They are a 1 1/5 weeks old and i know it's not burn because it sprouted looking like that. no other plants look like it. it's looks purple a little bit and i haven't fed any nutes yet. i have 2 6500k CFL 23w and 1 2700k CFL 14w bulb. i have that because i want a full spectrum throught out the veg. like i said my other plants look perfect. i have a inlet fan and a outlet fan 350 cfm so it has plenty of air. like i said it sprouted looking just like this.
the 1st pic is the one i'm wondering aboutView attachment 3020223 the 2nd pic is from the same batch and was germinated at the same time but what's up with this look.
Although the purple color is very odd for seedlings, I'd let it grow and see what happens. Remember although you have the same kinds of plants, they all have different phenotypes and will respond to the environments differently.
