Should I pot up my seedlings?
I started my seeds March 22, 7 weeks ago. I used a 3 oz plastic solo drinking cup (I cut holes in the bottom) and my mix is small gravel and perlite. It was cold and I wanted to avoid damping off, so I used very little soil in my pots.
They are growing under lights, but not on a heat mat. In spite of rotating them daily, they continue to lean. Also, when I water them, the mix settles and exposes the roots. I will post a second picture, but it doesn't show the roots very well.
I think it's time to change my mix and repot. I am considering adding soil to my mix, along with some orchid bark. The orchid bark has some big chunks, and I will have to sift it or break it up to keep it small. I'm also not sure if I should pot up to a larger pot. I have 2.5" plastic pots. The solo cups are 2" and about the same height. Is it time to start fertilizing?
Any suggestions would be appreciated. I'll be sure to take pictures when I do repot.
Thanks for your help!
