Hey I have a White Widow plant that i Topped in the middle of vegatative growth...It grew 2 branches from the main stem..Is it a good idea to topp again a month before flowering?? If I do, should I pinch off both growing tops?? Ive usually only top plants once...

My 3 foot White Widow was in a shaded spot for a while and streched to get to the sun light...It ended up falling over... It was in a pot but just the plant fell over...I staked it but some branches are limp now...Does anyone know what i should do to get the branches strong again??
