I have 2 sweet seeds Red Poison starting to flower. I have probably had issues with not great PH. Also had bugs for sure, and they might have got at the roots in one or both plants.
The one in the background is lighter green. Very light. New growth is even light. Flower area is black.
The one in the foreground is darker green, has more foliage, and does not have the black stained flower area. Flowers look 'normal' to me color wise.
Both plants had the same nute feed and H2O, lights, training, etc. But bug larvae might have affected one more than the other. That is the only variable I can think of, other than phenos and genetics.
Closer shot of the one with black stain.
Real close
Does this look like an operators error stress thing? Or maybe just genetics? Red P
