This answer is so simple - 24 hours of light is the problem!!!
24 hour light is such a BAD IDEA that anyone who recommends it, needs a good talking to.
With cannabis, 18/6 is optimum for plant growth, plant health and plant functioning.
Your poor old plant is plain exhausted and with a completely effed up metabolism.
Nothing, I repeat, NOTHING on planet earth can function normally without sleep, cannabis included.
Plants undertake extremely important metabolic processes during the dark/night/sleep time that are essential for plant health and functioning. These processes can not be done while the plant is in an "awake" state or period of lights on time. This is why it is vital to have a dark period during each 24 hour cycle.
Besides, cannabis can only grow so much during any 24 hour period and this growth tops out at around 18 hours, meaning running your lights any longer than 18 hours is basically a waste of electricity. Your plant will grow just as much, if not more, at 18/6, due entirely to having a normal awake/sleep/awake/sleep routine and will certainly have a much more normal and much more healthy metabolism, meaning her flowers will also be healthier and more potent too.
An exhausted plant can not produce prime flowers.
If you are keen, Google "photosynthesis" to find out why having a dark period every 24 hours is so vital for proper plant health and function.
Hope this helps, Organoman.
PS - having a night/dark time will also help keep your reservoir cooler too.
