Zero side branches, 4 weeks into veg?

Hey RIU so I currently have a Sour Diesel clone that is now 3.5 weeks into veg, and she is not about a foot tall she has literally zero branches to the sides, wtf is that normal? All 3 of the plants have the same structure! Is this just normal for the sativa side of cannabis?

Sounds weird maybe a freak pheno , i know u said clone but what seed bank is it from? I might want some if its normal for my sog.Any pics?

sadly no camera around me, ya likeit looks healthy and loving life, but just odd lol I was like well wtf I cant clone anything, even the cuts that are newer (in ez cloner) are showing same thing.....

as far as seed bank I have no clue-hehe
