+2 strains
I would defo keep them going longer. I personally wouldn't re-pot them at this stage as it might stress them too much or you could do some root damage. I'm novice myself but I like to look at potential problems and have a go at whats what. How's your watering? Are you following a wet - dry cycle?
I would also do your best to try and make that green house as pest free as possible. Difficult I know but it could even be pests that are slowing your girls.
