I planted 6 seeds In May. As of today they are now 6 weeks into flower. 5 plants ended up being female one was male and I got rid of it. 4 of the plants make up 90% of the canopy in my 8x12 grow room. One plant I noticed it looks like it started growing what could maybe be pollen sacs don't know why it would just start to do it now. Or they are maybe big pistils, and I'm worrying over nothing. Not sure it's my first time. First picture is the plant in question the rest are my other plants that seem to be doing quite well (just a guess don't have much to compare to other then pictures and videos online). I will be using a trellis net next time. Branches got heavy with bud and some are falling over so I had to tie them up. But any tips, anything bad you see, compliments, insults let em fly! Thanks
Below is the plant in question. It's sour diesel

This is white widow

Plants look good! Not a pollen sac in that pic; just a calyx like @Cap Stone mentioned. For the white spots on the leaves, can you inspect the undersides of the leaves with a microscope to look for pests? White spotting like that is often times spider mites.
