I've got an issue here some fan leaves curling down and a red stem issue. I've been using fox farm trio and phd tap water at about half strength of what the soil schedule recommends. Any suggestions? Thanks in advance !!
Hey Chief off the top of my head red stems\petiole can be caused by low phosphurous, is genetic, or could be triggered by colder temps. Here is a link with a great picture diagnosis that explains somethings that may help diagnose your issue. http://www.greenmanspage.com/guides/plant_abuse.html
