maybe stress has slowed the flowering ?
ive got a plant that is part of an auto breeding project , this plant didnt auto but the plant to receive the pollen did , so ive cut the hours on the plant to reverse to 12/12 and ive been spraying like a mad man 4-5 times a day/night lights on and lights off , my plant is in pro-mix hp with added perlite and even with all the excessive spraying its not showing any stress whatsoever , once it reverses i think it might make a good model pic for my c.s thread so people can see a reversed plant doesnt have to look fried like most peoples do when they make threads or youtube vids
anyway , point is , i see stress in your plant , it might be related to spraying with c.s or it might be nutrient related , burn or deficiency ??
keep on keeping on though , ive stressed some pretty bad and they still reversed and did their job just fine
peace
