Bottom Leaves Yellowing

HI, I'm Kean. I now facing problem with my green cos lettuce (Romaine). I planted the cos lettuce hydroponically with (DFT system). However, it bottom leaves turn yellow (yellowing). Also, there are some tipburn in my cos lettuce too. I have checked my nutrients level, especially nitrogen. All appears sufficient. Does anyone have any idea on the reason causing this? I attached together the picture of my green cos lettuce. Thank you.
