I came upon this thread searching in google.
I have third generation SLH (selfed twice, so S3 as they say, i'm not a breeder in the typical sense, I selfed to pheno hunt for myself, meaning I would never self seeds and claim them as stable or even worth growing but it's something I personally do) that produced a purple pheno. It yields low and grows more like a sativa in branching but produces an out of this world terp profile it's like lemon candy but with a slight sour skunk and pine, very loud. It's a lot deeper in aroma than I can really justify in descriptive words. Hope it helps. I will add, the bud structure isn't as indica as the OP.
I still have a lot of hunting to do, but out of three pheno's thus far, they're all very good in terms of quality. Personally enjoy the s3's more than the s2s but I didn't mess much with the latter. Although, again, I don't suggest selfing to breed or stabilize. It's just something I do.
