there are yellow-brown polka-dots on many of the leaves (Leaf Septoria???). See last image. Can you tell me what it is and how to treat? thanks

Hello ! The dots are sign of a Calcium deficiency. The red stems could be a Magnesium def but could also be a genetic trait (many WW are growing with purple stems) . So apply some Cal-Mag and if the stems continue to grow purple then you only had a Cal def. I hope it will help you. :grin::+1:

Hi there, that's pretty run of the mill cal mag deficiency, just add cal mag to your next few waterings it should recover in five to six days or so... hope this helps my friend, very fixable ! :rocket:
