OK this picture here is of my smallest plant, and it shows a bud - however the pistils seem to have withdrawn? The main cola is kinda like this too.. Now I'm thinking that its been pollinated somehow? Or perhaps there's another problem?

Does anyone have any pics or experience of what a pollinated female looks like??? The other 5 plants are fine, and aren't showing the same characteristics.

Would REALLY appreciate any sound advice on this one
