stop misting them when the light is on - ur causing ur ladies un needed stress - the water on the leaves acts as a magnifiying glass and it probably the cause of the white marks on ur leave = another thing! never have the fan blowing on seedlings, baby plants like urs - have good ventilation but never DIRECTLY have the fan air onto those - they are too small and it will create the plant putting more energy into stem growth rather than all round production - wait till ur babies are older like 5/6 weeks veg mark for that
