mh to hps

will i see any problems switching my vegging plants grown under complete mh to my flowering room which it hps only.

No. That's how it's done.

thank you for the quick hit back, that is what i thought but have you ever heard of anyone running into problems when switching plants over into another room with a different light source, like discoloring?

You will almost certainly see new growth appearing slightly pale when the plants enter their fast stretch stage over the next week or 2. That's normal, and you can even give veg fert for the first week of flower to lessen it.
Other than that, discoloration is a problem and you should look for possible causes.

i have been staying on top of my nutes because the great white shark gets real hungry when i switch them over so it should not be that, i guess i will have to look into other causes. thanks again
