How concerned should I be about purple stems?I seem to have some amount of purple stems on every plant I grow, some much more than others, and I suspect that I do run my plants a little harder on amounts of nutrients than I should. How concerned should I be and what should I do about them?

When Should I Consider More CO2?I flower my plants in a mylar lined box, roughly 2' deep by 4' wide by maybe 6' tall, using two 300W Mars Hydro LEDs. With that amount of light on the plants, would you recommend more light, or CO2 supplementation, and if so how much?

Methods to avoid stunted seedlingsDoes anyone have any favored methods to avoid stunted seedlings? It hasn't happened to all of my seedlings, but at least three crops have had this issue. I already use Coast of Maine seed starter, usually in small solo cups, before switching to the main soil.
