What's this pheno?

Hello RIU and others,

I have 2 strains from a few seeds I came across about a year ago.
From my research I have narrowed it down to 2 very similar phenotypes of Querkle. I flowered both moms, bud structure is slightly different and only one of them goes purple near the end. Seems to be a very finicky strain that goes about 9 weeks, but the sour/grape taste and aroma is well worth the headache.

I have not been able to find any information on this particular sour grape cut. Here are a few pics, the first two is a clone I put outside to take cuts from and to get a good look at this strain in good health. The others pics are a few I have in flower at week 5. My research leans toward these being a space queen leaning pheno of Querkle, but the descriptions do not thoroughly match up.
I'd really like to dial this strain in because it is my absolute favorite smoke to date, and will be in the garden for very long time. Any input from the pros?

There’s basically 2 main phenos, a grape one that’s short n stocky and a more cherry space queen flavored/scented that’ll be a little taller...not much but a little.... then it could be a mixture of the 2.. be able to judge them better when there closer to being done... kinda hard to tell until then...as long as you keep them nice and green and no defs showing until about the 6 week n beyond mark; that’s bout dialed....

Day 30 and 45 are when sub recommends some molasses or any other sugar product... i stuck to that for the most part n had pretty good luck....

Excellent post thanks.

This pheno is the stretcher but no cherry flavor. Best I can describe is a sour grape with a slight menthol effervescent. Has all the Querkle traits tho including the purple under the leaves around harvest time.
I'll be testing the difference between molasses and raw coconut water at days 30 and 45 as well.

@whitey78 Here is a small one i pollenated. This one is at day 50.

Just about fully seeded and ready.
