To me, it looks and sounds like senescence is setting in. If you can get a look at your trichomes you'll get a better idea how far you are from harvest. Looking at RQS they say 30-40 days flower. Given you topped, that puts additional strain on the plant's system. both in terms of healing but then as someone else pointed out, the additional flowers take energy to support. And that isn't even considering the slight genetic variations from seeds. All that impacts the timeframe a bit.
Their site info on these F1's is garbage. XXL yield... What does that mean?!
When I started, no one would sell F1 seeds, they're not considered stabilized yet. The F-number (Filial generation) tells you how stable a strain is.
F1: First-gen cross, great hybrid vigor, but expect high variability in traits (some lean toward one parent, some the other).
F2: More genetic recombination, good for pheno-hunting, but even less predictable than F1.
F3-F5: Selective breeding starts stabilizing traits—less variation, more uniform plants.
F6-F8: Highly stable genetics, meaning plants grow nearly identical every time. Perfect for commercial & medical growers who need consistent potency, yield, and flowering times.
If you want variety and unique phenos, go F1-F3. If you want reliable plants, go F6-F8. An F1 hybrid from a lineage as complex as (Blue Dream × Blueberry × Amnesia Lemon Haze × Black Domina) is likely to be quite heterogeneous, meaning its offspring will express a wide range of phenos due to the diverse genetic background.
