may not be fastest growing, but looks healthy.
i'd add more perlite (or similar) to your substrate next time... if soil-like capacity, then you want roughyl 50/50 with something like perlite. if it's coco, you can do 70/30 because coco holds less water per volume.
this may improve rate of growth in future. can alawys improve on feeding habits... so i'm sure it can be faster but tough to tell you what to do with so little info... i think happier, more vigorous roots will be a good boost though.
