So I have BushDoctor CalMag and have been watering at the recommended 5ml/gallon in RODI water, should I double it? I've been leaving the soil on the drier side but I can up the frequency of waterings.That looks like the beginnings of a CalMag deficiency to me. The yellowing leaf looks like a calcium issue, and purple serrations are usually a magnesium issue. It's early but will spread fast. Calmag should stop it.
If you don't have CalMag but you have prilled dolomite then mixing it with chlorine free water to about 75ppm and using it every watering for 3 or 4 waterings and then dialing back to every 2nd watering until harvest should fix it up.
Act quick before you start losing leaves.
