I know I must sound like a broken record for those who have read what I have said in any number of threads but that is one of the reasons why I do not repot. I start my seedlings out in the largest pot size used for a particular grow and when I pick pot sizes I always say think like a woman who is looking for a guy just for sex ….. bigger is better.
Once your plant’s roots begin to circle the pot they are in your plants will be under some degree of stress. That means each time you allow your plants to fill the pot they are in with roots and then repot you have allowed your plants to becomes somewhat stressed and then you risk shocking them on top of it my repotting.
I would say it is likely that your plants will be fine if given a little time. Maybe try backing off on the water slightly for a short while and if they do not perk up or give any sign of wilting more than go the other route and water them well but my guess is they were shocked by the double repotting and then most likely both times you gave them a real good soaking after repotting so there may be some over watering problem added to the repotting shock.
My advice for the future would be, and some will not agree with this, is to pick out the largest possible pot size that you can use and go with it from say one. If there are space restrictions that means you will still likely have to repot at some time because initially you will have multiple plants and then be removing males but while having your largest number of plants you will need smaller pots to get them under your lighting still use as large of pots as is possible and then only repot once after weeding out the males and then putting your females in the largest pot size possible that will still allow you to fit them under your lighting.
I try to never go under 7-gallon pots and prefer larger, though I will at times if I am growing some smaller strain or just pop so many beans that like I mentioned to get them all under lighting I am forced to go smaller initially.
I also prefer to buy feminized beans so I can then go larger in pot size right from day one because I will not have males to weed out and I can then fit all the larger pots under my lighting.
Another reason I like larger pots is it makes watering easier and give you some cushion, some margin of error that you do not have using smaller pots. When watering it is good to give plants roughly one third more water than the soil can hold. It will of course drain out into the try your pots sit in but then I leave it there for a few hours. The reason I do that is often a percentage of water applied will rush through your soil and into the tray below the pots and not really moisten the soil so if you leave the pot sitting in what ran through for a few hours it will then wick up moisture until all the soil is moist and then I will pour off what water remains in the tray. I may still get roughly one quarter of an inch of water that then drains out of the pots but I leave that and some is sucked into the pot as the soil dries and some just evaporates.
But with a large pot with moist soil even if your plants are small and do not have large root structures as the top of the soil and areas closest to the roots dry out moisture from deeper in the pots and in areas where when the plants are younger/smaller and have not sent roots out into yet will wick up and towards the dry areas and that can be the difference in finding wilted plants one day because you under watered them the last time or forgot to water them one time or for some reason were unable to water them one time. The additional water is not enough to cause over watering problems or root rot and you can still let them go long enough to get slightly dry, like herb plants do like somewhat, so there is no danger in doing it and as I said it gives you a cushion for when you for some reason or another get behind on watering. Also later when the larger pots become largely filled with roots you do not have to water nearly constantly to keep up on the plants water needs like if you grow in small pots and the plants can suck out all the moisture in very little time due to a lack of an adequate amount of soil to hold moisture for your plants for at least a reasonable amount of time.
