preflower questions

A plant started developing preflowers around 1.5 months of growth. No pistils were visible so a little after 2 months the photoperiod was changed to 12/12(The photoperiod may have been changed too early). Now after about two weeks every top has several pistils as well as almost all of the branch internodes on the main branches. Although, the preflowers along the main stem do not have pistils and continue to appear as small as when they first developed.

I have read that pistils form from the tops of plants downward. Do you think the pistils could still form this late or do you think the lower internodes contain male preflowers? It appears that all of the preflowers since the change of photoperiod are pistillate.
but has these on lower branches.

I'm having the same problem.

Its not a problem guys...totally normal. The pistils are gonna keep developing all the time...this is good. Cant see any male preflowers though. Keep posting..

any more pics of the whole plant

They're kind of dark and I apologize. My camera isn't the best.
I had to bend it because it was getting too tall for the space.
