i think you have to make a water schedule for your plants.....sure thing, leaving them two days with no water can't cause any harm BUT you must NOT water them everyday....leave them unwatered for a bit....this will make the roots thirsty eager for water, as a result the roots will search for water even deeper and develop an even greater root mass and root system, your plants will look healthier....the basic rule of watering is to water whenever the first 2 inches of soil feel dry to the touch....try not to overwater.....i unserstand you love them and want to grow as fast as possible....by overwatering or watering too often you're not helping them but stall their development...
