Biscombe
If they are ready to go out, then maybe they are suffering from humid/damp conditions indoors and the fresh air & wind will help. I always find that if I water pots from the bottom up (i.e. in saucers/trays) they come out healthier than those watered over the leaves; I think it encourages better roots and doesn't leave dampness under or in between the leaves.
:-\ That said, of course, I still get lazy and soak things from the top in the greenhouse (mustn't make splashes in the conservatory!). :-\
