Tiny plant? or normal? Guava auto fast buds.

Whether it is techinically a dwarf or not would require more than a set of eyes unless it is extreme... e.g. in pic #3 that kinda looks like the node spacing of a dwarf, but then you have somelonger internodes elsewhere... A runt isn't necessarily a dwarf, but still not what you want in a canopy, obviously. light intensity, nutrition, irrigation habits can all cause greater inconsistency in outcomes for less robust plants. Some can power through a multitude of less-than-idea circumstances. Is what you see genetic predisposition or environment? You might be able to have a good guess but certainty is unlikely. if you are confident in consistently growing suprmemely healthy plants and these minor leaf symptoms are rare for you to see, then sure.. probably some sort of weird genetics. maybe you can figure it out, but is it worth the trouble? less experience may require a bit more self-reflection. I'm not assuming either or anything between.
