iv had that 2 bobmaf, i think it might be a grow neer by or maybe the plants got a bit of genetic damage form repeated cloning and that's produced 1 or 2 hermie pollen sacks. iv heard that repeated cloning from the same genetics can produce mutations.
found this on another post by "whutever"
"Hmm.. as far as I know plants have the same problems as humans.. but im not sure.. though a plant may have the same genetics, the DNA is always being damaged (failure when copying amino acids into DNA), but whilst still repairing itself it cant maintain the ratio of damage to "heal".. so the the longer the same DNA has been copied (cells) the less chance the plant will have of continuing its abilities such as fighting off mold, insects. etc.. its something that is studied right now on living organism were they try to stress a organism (mostly bacteria) to make it "heal" faster then its being damaged.. however im not sure how or if it applies to plants.. but still.. worth mentioning i think
