Nikolaus Reviewed by Nikolaus on 12-05-2008. Which deficiency is it??? Need Help Please!! Hey guys anyone call tell which deficiency is it? Started first with the older leaves. They're getting yellow, curved down and the veins are still very green. I managed to get the temps and humidity okay. Watering every 2 or 3 days for now on... Please help! Doesn't seem like Mg deficiency to me... Rating: 5
