I went looking around after I asked here. Some people think it's an indication of potency. I was just wondering what y'all thought about the purple. Seems like I see it sometimes from seedling on out.
Keef, that triple Lemon had the 4 lobe type stalk. That's the shadowing that showed up in the 1 pic in my journal. But some of those plants have the purple lateral and intercalary meristems. The side and in the middle. I've had them in natural light. The hue pales but it's present. I have no photo proof tho lol. I was thinking back to running HID in the past and only seeing this trait when lacking P or it was cold at night. But in this case, my temps are ok- no major swing and I'm pretty confident my pH and P are ok. It seems more prolific than I remember.
Most people think it's low P or temps/pH. But actually low temps create the lock out, right? I was thinking genetics because some plants have that coding. Like GDP or what was it, Bubba Kush? Anyway, that would guarantee expression but I pondered LED and it's amazing spectrum being a trigger for it. I'm pretty sure this is all just my sub conscious trying to get me to order a really expensive piece of lighting with spectrum control...
