Hi. Thanks in advance for your help.

I grew my own seedlings for the first time this year. I've already planted a lot of them outdoors, including several strong tomatos that are maybe a foot tall and nice and bushy. However, I have another dozen or so tomatos that seem to be stuck at around four inches tall, also with pretty good leaf growth but otherwise small and unremarkable (and slow). Should I give up on them? Are they just slow - or are they somehow permanently weak/stunted? Any thoughts?

Thanks!
