Is the new growth green and the old growth yellowing? From the pictures it look as so. I could be a nutrient deficiency try and add some diluted fertilizer next time you water

the problem is a molybdenum defiency.
it is listed here with picstures that match your own.

A Molybdenum deficiency causes leaves to have a pale, fringed and scorched look, along with weird or retarded leaf growth. Yellowing of middle leaves can occur as well as twisted younger leaves which will eventually die. Molybdenum deficiencies frequently resemble a nitrogen deficiency. A Molybdenum deficiency shows older chlorotic leaves with rolled margins and stunted growth. Looks like a nitrogen deficiency but with the red tips moving inwards to the middle of the leaves. Molybendum deficiency will usually show up in the older to middle aged leaves, then it moves to the young leaves. Generally a molybdenum deficiency occurs when sulfur and phosphorus are deficient.
Either that or posibally a Potassium deficiency
Having to little of Potassium in your plants causes the plants leaves to show retarded growth and show a scorched tip and edges around the leaves. Plants may stretch and your branches can be easily broken or weak. Dont get this deficiency confused with iron, because it almost acts like iron but to tell the difference in the two is: for potassium the tips of the leaves curl and the edges burn and die. Older leaves may show a red color and leaves could curl upwards. Dead patches (Necrosis) can happen on the margins of larger fan leaves thus, the leaves will eventually die off and turn brown. The Older leaves will show different patches of color (mottle) and turn yellow between the veins, following by whole leaves that turn dark yellow and die. The plants overall growth slows down, mostly when they are in vegetative stage. To little amount of potassium also slows the growth of buds during flowering stages. Dark edges will appear around the edges of the leaf when the deficiency is starting to happen. When your Relative humidity is low, you can almost bet your going to soon get a potassium deficiency from your plants perspiration.
Potassium can get poorly absorbed when having too much Calcium or ammonium nitrogen, and maybe cold weather. Having to much sodium (Na) causes potassium to be displaced. SO keep those in mind Parts affected by a Potassium Deficiency are: older leaves and leaf margins.
