Shiny leaves = more than adequate nutrition, so ease up on the foliar feeding.
Foliar feeding should only be necessary as a quick fix for major deficiencies, not a day to day supplement, the roots do enough for the plant.
Growing at 24/0 is bad for plants, they NEED sleep to function properly, no matter what is out there on the internet.
Without sleep a plant can not complete its photosynthesis cycle and without completing photosynthesis, the plants will not have a correctly functioning meetabolism.
A plant with an incorrectly functioning metabolism will never grow to its fullest potential.
18/6 is optimum for cannabis.
Cannabis NEEDS sleep.
Could you imagine living for days/weeks/months without sleep?
Everything on planet Earth has a "circadian rhythm", without one, things go haywire sooner or later.
You will not lose anything by going to 18/6, in fact you will gain much due to your plants having a correctly functioning metabolism.
Be kind to your plants and give them the sleep that they NEED, at this stage they must be getting close to being completely exhausted!
