You probably aren't going to get many responses if you only want advice from people who would classify themselves as an expert. There are many knowledgeable people on here that would be happy to help, but not so many that would call themselves an expert. Those who do probably aren't. Hope this helps for future posts.
Non expert advice: The plants look fine(nearly all seedlings stretch in the beginning)You could have started them in a smaller container then transplanted them with the stem below the soil(putting the stem below the soil will cause the stem to grow roots in a few weeks/keep the plant from falling over). The only thing I could suggest now is to make sure the plant is supported so that it doesn't fall over from any wind or misting, and to bury the stem the next time you transplant them.
