hey fellow growers would any of you kind people now what would cause my plants to wilt within 10 min of watering then about 6 hours later they look fine again, they are about 5week old clones they rooted well an have been growing fine for a few weeks they have only wilted after the last 2 waterings, i dont think it is underwatering cause i wait till the top 5cm of soil is dry an they wilt after watering an my soil is'nt soggy either so i dont think it is overwatering. what could it be?
