Changing bulbs during flowering

in my 3rd week of flowering Using sunmasters super high output hps but was acting up so returned but didnt have them in and was given agrosun super red hps, will having a slight different spectrum casue any kind of shock or stress

No, it wont.

None at all.

i use 2 400W hps grow bright bulbs, and one 400W CMH bulb and they are killing it, they do seem to prefer the CMH bulb though! differnt spectrums wont hurt, they help if anything.
