They look like autoflowers, you do not transplant them, u put them in a nursery pot you intend to do your whole grow in, see the first plant? It is dwarfing out bc of the stress and double transplant, for large autoflowers you put in 3gal pots, smaller strains go in 2gal pots, your others look a bit better, before they go into flower they stretch and they look like that's what there doing, allso if running full spec, light it has red and ir in it, again this can and will cause them to flower prematurely and/or dwarf out, if running autoflowers you want a 2 cycle light bc they need blue light in veg and since blue light has no red or ir they can grow properly, I grow them bc my needs are small and we can only have 3 plants in flower so my grows are perpetual in other words once the first 3 go into flower closet I start 3 more and it would be ridiculous to run 3 photoperiod plants, autoflowers are not photoperiod plants and are not run the same. Good luck.
