ok i'll try that but it got cold about a month ago, down to about 45F and i think it locked out the phosphorus. i will post a picture tomorrow but if it's not that then i don't have any idea. it's only on one plant but it's a female so i wanna get it taken care of if possible>>>>>>

Try foliar feeding it with that solution, you should notice a difference much faster then soild feeding IF that is the problem and yes you don't want to lose a female and you want to solve it before you go into flowering. I had a "problem" with just one plant 4-5 weeks into flowering and never was able to really solve it, foliar feeding was out because of the flowers and I tried to juice it with some nutrients but nothing worked, it didn't die but didn't look too well either.
