Knots at the tips
Some, I should say a lot, of mt dreads have been doing this too. I'm 4 months in, and they eventually form into little pebbly balls at the end of your dread, then the res of the dread starts to form. Once it goes through that stage, it starts shrinking in on its self and your left with a ziggy zaggy dread with blunted end that does hold the water more. I love how they look. just pay extra attention to them to make sure they are drying. Once I'm able ill post pics of their stages cause I have all stages on my head.
