baking soda is sodium bicarbonate. that has no potassium in it. i would say first check your pH. if your pH is off, then flush the plants thrououghly. maybe even switch pots(if they are early in growth.) if they have a good pH, then get an npk fertilizer that is high in K. If you dont have any of this and the condition worsens considerably b4 u can get some, u can sprinkle a small amount of wood ash (from fireplace) on the soil and then water.
