Yep... I agree. According to Jorge Cervantes "Grower's Bible" (I love this book) a Phosphorus defieciency:
"Stunted and very slow-growth plants. Dark bluish-green leaves, often with dark blotches....."
It says to treat by lowering the pH to 5.5 - 6.2 for Hydro or 6 to 7 for clay soils or 5.5 to 6.5 for potting soils so phosphorus will become available.
