Deficiency of nitrogen and phosphorus? or overfeeding?

Do you have a diary for this grow? - Never mind, I found it.... You have no information in it about what nutes you've been giving her and this is probably critical. That being said, I'm going to agree with Organoman here - it's a potassium issue, not phosphorous ... and you definitely are NOT going to see the yellow leaves turn green - especially after only one dose... You might want to consider sprinkling a tablespoon of Langbeinite on top of your soil (done once a month throughout the grow avoids this deficiency) ... it's got a NPK of 0-0-22 and should help considerably... Good luck...

Bottom leaves going yellow is fairly normal. Top leaves going pale at this stage is likely a potassium deficiency. One dose will not correct issues overnight! Damaged leaves will not recover, no matter what you do, you can only stop it from getting worse.

calcium lockout ( could be hunger too ) or root bound . either watering regime is bad , usually its when people water while pot is not light yet to get such result ... check run off, when situation has many path, knowing whats inside of pot is only way ...
