I dont think thats a good idea unless you are planning to flower from seed in which case you would want to keep it under 12/12 lighting.

IMO if you want a decent sized plant you should keep it under either 24/0 or 18/6 light constantly for a month or so, give it time to veg a little and then switch the light to 12/12 so it can flower.

but to answer your question, i believe you are stressing the plant by doing what you are doing right now.
