plant flowering, nitrogen problem, plz help!!!!!!!!!

Hey thanks for reading, my plant has started to disgard the fan leaves, it started from the bottom and has since worked its way up, ive lost alot of green and my plant does not look well at all, *NEVILLES HAZE*

i heard 1/10 of urine/water works but i know that its also a weedkiller and dont want to destroy my baby.

please help, and if any "brand names" are possible so i can purchase.

thanks very much

scotland loves you

 

THE FULL PLANT IS TURNING YELLOW LEAF BY LEAF !!!!!!!!

i think its a nitrogen problem but PLEASE tell me how to correct this


thnx much

 

Yeah its in bud but onlt a weeek or 2 and the leaves are losing colour at a rapid rate, nevilles haze takes up 2 16wk to flower properly and i dont think she will last that time while this is going on. ive lost about 6 main fan leaves and i dont know how many other ones

 

this is the 3rd week of flowering now.......ive been using biobizz grow/bloom and topmax.

my local supplier told me if the leaves lose their colour then go crispy its a feeding problem.......ive bought a thermometer and think the temp may be a little high, aslo been told if im usin all those nutes it shouldnt be a N problem at all

i thnk my buds have just stopped growin, seem to look the same as last time, everyday

my full plant is yellowing im in very very bad need of help, i dont want her dying on me after all this time....................any suggestions??

 

even the pistills are starting to brown on the lower parts of the plant
this is worrrying seeing as its not even the 4th week of flowering

i think she may be too far gone to save her, which means its a waste of my time any money

i really dont want her to fail, but its serious and everyone keeps telling me different problems

wish i had pictures

the leaves start green but from tip to node turn yellow then curl under and crisp. im in a bad spot
