Some issues..

hey yall,, i have 3 plants growing so far in my FIRST indoor grow. i made a lil grow box for them with cfls. the oldest plant has a problem. she is a week old. she is a little lighter in color then her sisters. she has yellow tips, and on the sides. the the top leaves are growing straight up and they are small. But my other 2 girls that are 3 days younger are happy and the new set of leaves are big and not growing straight up. just dont want one to die. all the same strain. here are some pics.... the first 2 are the sick one, followed by the 2 sisters that are healthy and happy. thanks..

Her top leaves are growing straight up, and the bottom are drooping



she is sad.

And this is one of the happy girls. the leaves are bigger but she is younger. and the top ones are growing normal not up.



and here is the last healthy girl. nice normal top leaves.

and my little grow box so far.

That first one will be fine, soil a little too hot for it. Looks like Miracle Grow with the osmocote ball there, good luck!

its scotts soil. i ordered some of that fox farms stuff and will transplant into bigger pots and that soil when it gets here.
