Does this look normal or is my light too bright... maybe it's nute burn??

Please look at this Pic... it's my last plant and it's in 5th week of flowering. The leaves are turning very dark and looks like nute burn... or am I just crazy and this plant looks normal.. it's bag seed but definitely Indica dominant.. how much longer do you think?? Any advice is appreciated... Pic attached...

Yes too much . Far to green .
