week 6 of flowering white russian HELP!!!

hi i'm in to week six of flowering a couple of white russians amoungst others,everything was going along nicely until i noticed new shoots growing out of all the bud tips,any body have any idea of what this is as the plant seems to have stopped budding?
1200x1200grow tent
soil grow
600 hps
100mm fan/carbon filter
advanced nutes
this is my first attempt at an indoor grow having only grown autos in a green house last year
the first picture is of the two russians(the plant on the right is the one with the new growth) pics 2 and 3 are of the new growth
thanks for any help

Are you 100% sure your timer is functioning properly?

They may be reverting back to the veg mode..

Check for light leaks too.

thanks for the quick reply bad boy,to my untrained eye it dose seem like its revegging i think the light issue is ok as the tent is in a dark garage and the timer seems ok.am feeding advanced nutes sensi bloom a+b overdrive +just water and molasses every three feeds.

come on guys any ideas,will this plant upset any of the other plants in the grow tent
