skinny yellowing leaves

[SENS1MILLA]

my biggest plant has shown some major changes in the charcteristics of its leaves. The leaves are growing increasingly thinner, curling upwards, and yellowing at the veins.

look at picture 1 for a leaf that is lower on the plant. notice it looks large and healthy.

picture 2 is one of the more recent leaves. it is very skinny, curling upwards and yellowing.

Any idea on what is causing this???

I had a similair issue when i was under watering. Thats just a guess though.

thanks BBB, but im pretty sure i dont underwater them
anyone else? could this be a pH problem or a Mg deficiency?

that's NOT Mg defficiency.. hmmm I will have to figure it out. I brb with an answer.I don't know if I have one. If I had to guess it has something to due with your pH probably though. I got a rule of thumb lol.. if in doubt it's probably the pH...

sulpher deficency is the best i can come up with, but then again those aren't really yellow enough to be that definitly.
