ive not yet had a chance to repot my plant but will do it tommorow, im sure that will help. in the mean time the prblem with the leaves is spreading. its now effecting the bigger lower leaves as well, inbetween the veins the leaf is a paler, more yellowy green and is more translucent. is this purely down to lack of root space or what? im mostly curoius because i want to fertilise it again but am anxious not to poisen it.

thanks for the advise though fella :-]
