Phosphorus deficiency

after looking at the plant problem chart in faq I have concluded 2 of my plants have a phosphorus deficiency. I know a picture tells a thousand words but I have no camera and I apologize for that. Basicaly the damage is the same as in the picture in faq but it is slowly spreading from the bottom up, I have removed the brown crisp foliage. I am using advanced nutrients and this is my fourth time around. My question is sould I just increase the amount of nutrents I feed them? Is it possible to put more micro in the mix than grow? all opinions are apreciated thanks.

mirco - 2-5-10
grow - 7-0-4

add some bonemeal if its PHosphorus deficency

make sure its not ventalation and air circulation (need a fan )

thanks ill make sure to cut a hole for vent the plants are in a closed room with a fan exaust is over the trusses ill cut a whole in the cieling ( white house wrap) and ill transplant with bonemeal.
