thanks a lot, its just annoying spending so much time and then to notice a flaw in your system, i just needed the advice of someone else, i was panicking lol.
i have three separate lights all on the exact same light cycles, all three on separate timers.
one of my timers (i must have bumped) started turning my light on from a 12/12 cycle during my third week flowering, to turning on at about 18/6.
i noticed this by my plants gaining new growth...
