Found this thread and I thought would try asking for some advice about my Alocasia cuprea.
As in in the pictures below, you can see that some leaves are showing strong signs of 'veinal chlorosis".
I am not sure this is it, but just referring to the problem.
I have had the plant since last November. In the beginning my Alocasia shed some leaves, which wilted slowly yellowing from the edges. I thought this is normal since new location and winter season.
Since March, 2 new leaves sprouted ,and 2 other are soon to roll out, however in the past 10 days plant started yellowing from the leaf veins. Out of 9 Leaf, 4 are showing these signs.
Any help and insights would be highly appreciated.
