I'm not really sure how someone could know this plant has gone from flower to veg to flower - your diary doesn't give this information! If she's a photoperiod, yes you're giving her too much light... cut it back to only 12 hours of light and 12 hours of complete darkness.... and don't change that. You should also try to take photos in normal light so we can at least see the natural coloring of her leaves - that would give us additional information about what's going on with her. .. as well as a picture of the entire plant! At this point in her life, she'll be wanting a lot of PK so try to get that into her feed as well... and cut back on any nitrogen you're giving her... Good luck!

High Popol, This plant has been going from flowering back into vegging. The name for this is revegging and it happens when you switch to lights on flowering mode 12/12 and after she started to flower move lights back to vegging mode (more than 15 hours light a day). It could be a problem with the light settings. Or there could be a light leak in your grow space that disturbs the dark period. Without 12 hours straight darkness she will not be able to flower. When you can not make sure that you give the plans 12 hours straight dark period for flowering you can also choose autoflowering strains. These strains do not need a dark period but grow the best on a 18/6 light schedule.
