So I have a couple of week old plants that are starting to yellow at the corners of their leaves. One is very yellow the other is still mainly green with just a yellow spot on the tip. Sorry, no pics. I water about once every two to three days, basically thenever the soil is dry. I have a 400 w hps about 20 inches or so away from the plant with a fan pointed at the bulb. Does anyone have any idea what could be contributing to this. Plz help
