I've searched and read on here for months now, and even so I still come up with questions where I've already read all the threads and there is conflicting answers or still unclear. Also, when it's YOUR plants, it feels good to just ask.

For example, red veins/redness on main stalk. Blotchy rusty spots. Those are a couple of issues I'm studying because I have both of those, and it's everything from too much of this or that nutrient, or nutrient lockout, or nutrient deficiency, or even mold or parasite.. I think I'm going to have to resort to posting pics in the plant problems forum even though there are dozens of threads already..
