I’ve got my Snora Bora in flower right now and they’ve developed some really prominent red stems.
Earlier in the grow I did accidentally let them dry back too hard and had some pretty serious leaf die-off, but since then they’ve bounced back and look relatively healthy overall. Bud development is coming along fine, no major issues besides the stem color.
That said, the stems are still very red — way more than I’m used to seeing.
Trying to figure out what’s actually causing it:
Is this just genetics showing through (anthocyanin expression)?
Or could this still be lingering stress from earlier issues (watering, nutrient imbalance, etc.)?
Anyone seen this before during flower? Did it end up affecting yield or quality at all?
I don’t know for certain but I lean toward genetics with some contribution from soil conditions/nutrients. I have never had any problems when the stems were red.
Yeah soil could play a part. I’ve been dealing with gnats, so they’ve been bottom-fed. Air pockets may have played a role as a result. Everything seems copacetic now, and they seem super healthy - so I am leaning on genetics. I know the 89 Northern Lights 5 Bx was quite colorful for some, so I am hoping for that.
Did the color also transfer to the buds, or was it just the stems?
I’d say genetics, my BlackBerry girls usually express very vivid purple and red stems, petioles, and buds get almost black. Stress could do it, but I don’t think you have stressed them enough to do it. Keep in mind that LED lights can sometimes cause red stems. From the last BB girl grow.
Here is a Pineapple Cream Cake and a Blue Dream, both ILGM, good examples of light intensity causing a bit of red, in my BlackBerry girls, it’s much more purple and darker. Another way to tell is are stems red on bottom? If not, it’s lights, if so, genetics or VPD. Lights will only color surface facing light.
they have green trunks at the bottom (and stems) - but I’ll try and source some mag. any good DIY sources for mag? I am leaning toward Cocoa (not coco) - that’s my source for mag
Red petioles can be genetic or from a number of other things. These started to become almost common with increased use of led and uv lights. I have seen people suggest high intensity lighting as a potential contributor but I think it could easily be a reaction to specific wavelengths or a combination of specific trait within a genetic makeup that is reactive to certain conditions. Much like certain strains being more reactive to cooler temperatures. If from nutrient deficiency I believe its most probable to be a phosphorus deficiency or lockout.
If we don’t see any other issues causing concern we would typically suggest disregarding the red petioles as a major concern.
