This is her 26th day from seed. 2 days ago I started noticing the color changing on the leaves. Don't know what it could be as this is my first grow. I am using a Mars hydro 144X 5 reflector and it is 20 inches away. Using a 5 gallon bucket for deep water culture with plenty of air reaching the roots. I am using techna flora nutes at 1/4 strength. The Ph has been between 5.8 and 6.3. Any help is appreciated. Thank you
