New Leaf?

I noticed my little albo is starting to have some new growth wanting to pop out about 2 weeks ago and it doesn’t look like it’s changed since I last saw it. My other plants seem to push out leaves rather quickly even my thai con. I know the albo is slow growing but do plants ever just decide to stop in the middle of trying to make a new leaf? I usually keep my humidity chamber around 80% and I water with foxfarms big bloom every 1.5 weeks. Please help
