can you give details on how often you water , room temp, type of water you use to water plant , ph of soil and water. MG soil should be buffered for ph , but who knows how long it sat around till you bought it.A swing in ph can make leaves claw like that.Did you use different water this time? Also what type of plant is it bagseed or did you by a certain strain ?I have had different auto's do this. i never was able to correct it.With there short life and all.But they yeild to full potential at the end. Some strains seem to have droopy curled leaves later into flowering.But you are not at that stage yet.Are you still in veg or early flowering?Have you used any nute's yet? Also add anything eles you feel might help.
