this is the second grow that this happens.(the pic is from the first) seems like something is eating inside the leaf. (1st time that occurred on the crop as i remember i treated it with soap water...then jusi i ignored it )
got any idea what it is and any solution?
thanks
looks like leaf miners, use some insecticide soap.
if there is no improvement bust out the big guns, get some pyrethin spray, I use Dr.Doom pyrethin spray.
