PH balance your water and you need your essential nutes man N P K all day!

You're only giving them a half bottle of water every four days? As in a 16oz. bottle of water? If so, 8oz. of water every four days is not near enough. Get a gallon jug and let it sit out a few days with the lid off to get the chlorine out of the water, and ensure your pH isn't too high or low. To check the soil's pH, simply check the pH of the water that ends up in the saucer.

if you just get a gallon water jug and fill it with tap water and leave open constantly the chlorine will evaporate by the next time you need it and then just refill it again....then when watering your plants slowly water until you have run out on the bottom of your pot then dont water again until the first couple of inches of soil feel dry...or use the technique of lifting you pot if it feels light water it if it feels heavy dont... or just get a soil moisture reader and water whenever it tells you too
