Indoor grow, pots too small, late in Flower

Hey all, I am doing a small indoor grow in a 2x2x5ft tent. 2 plants about 3 ft tall….currently 46 days into 12/12 (probably about 39 days since white hairs). Starting to notice some wilting lower leaves, some curling/crispy leaf edges….I think my problem was way too small pots (probably only a gallon size) and possibly over watering due to small pots. Any suggestions or just hope for the best and ride out the next couple weeks?

 

Thanks. Appreciate the response.
