Hey growmie,
For Day 23 from sprout, your lady is definitely on the smaller side, but not alarmingly stunted. Autoflowers can vary a lot depending on genetics and environment. Yours looks healthy, compact, and already showing early flower sites, which is normal for some autos around week 3. A few things could’ve slowed her a bit: Light stress or distance early on, Slight overwatering or cold nights, Starting in a smaller pot and transplanting (autos don’t always love that) But don’t stress, many small autos still yield well with proper care from here on. Focus on dialing in your watering, airflow, and feeding gently as flower ramps up. She’s alive, green, and stacking, that’s a win
