Out of curiosity, what are you growing? It definitely sounds like it's in the genotype if they are all the same. >>>>>>>>>

A batch of seeds from a friend who got them all from the same plant last year. All the plants grew out the exact same except for this one plant. The pistils started out white but as they grew out turned purple and the flower development is different from the rest, my guess is this particular plant is Indica dominant.

Most of the large sun leaves have died off but the branches are very, very heavey with small sun leaves bunched up around the flowers. All of the other non clones had very large and fat leaves all the way up until harvest and the buds were well developed with minimal leaf material surrounding them.
It is possible he got this particular seed from a different source or it could have just been laying around. He just handed me 20 seeds and asked me to grow him a nice plant.
