Honestly, I think she's probably got a long way to go...she's super green, lots of white pistils, almost no bleaching yet. If that were my plant, I'd treat her like she had 16-20 more days left before cutting down...another feed won't kill her and I'd leave every leaf on.
You gotta remember, if these are F1 seeds, there are going to be a lot of pheno types. Some are going to lean towards the dwarf autoflower genes and some are going to lean towards the Haze genes. If this is a haze heavy plant, that means it's only been flowering for about 50 days, or 7 weeks. Most true Haze plants take 14-20 weeks to flower, so if you just guesstimate what an auto should do, I'd say 12 - 14 weeks seed to chop would be reasonable, accounting for 15-30 days of veg before preflowers show up.
