they will make it, its nearly impossible to kill marijuana plants. It's easy when your new to fuck them up real bad though. lol. not saying yours are fucked up real bad, because really they are not, i was just making a point. You should use the lift method to determine when to water and when they do need it give them a good watering. Overwatering is watering too often, not too much at one time. I use as much water maybe a bit more sometimes as the containers size usually.
