As the title states, I would just like to confirm what I believe is a phosphorous deficiency before I proceed.
Strain is Nirvana's Master Kush. About 4 weeks old. I'm ruling out ph problems as its sisters (hopefully) receive the very same nutrient solution. Am I correct in assuming this? First pic was from last night, the second is from today. Same leaf.![20160313_193726.jpg](/data/attachments/2731/2731413-332a64224e16aeaef7da6d34fa719380.jpg)

Can someone help me out?
