Did you veg these plants longer? (giving roots more time to outgrow the pot) Do you use a micronute additive? Do you know the ph of the water and run-off?

Without more info, my guess is it's either a purple strain of some sort, or plant is not uptaking nutes. A careful transplant to a larger pot is likely the solution. (use a non pre-ferted soil mix if possible) A quarter-strength veg-fert spray would likely help until you transplant. A fine spray, not a drench...raise the lights till moisture on leaves dries, or risk burning the leaves. This is not a recommended end-all solution, but a temporary band-aid till problem fixed. Once or twice likely ok, but more would be pushing it.

There are really only two times a cannabis plant sheds it's leaves so early in flower. Low light, as in deep inside the canopy...or stress. By the sounds of it, stress is more likely.
