oh, about the watering every 4/5 days is about normal. try to learn from one time watering your plants when they have done well for a few waterings to find out when the start to drop leaves. Is it day 6,7 or 8? that way you know to water a day or 2 before they start to drop as these plants like a bit of drying out but not dropping leaves. You will notice after you have let them dry out a bit then after a water the next couple days after that water the plants will explode with growth... Now... you are dealing with a growing plant so....this water cycle can change a day or 2 through flower as the root system grows and takes in more water. you see...now you are turning into a farmer that adapts....lol...
