Critical Northern Lights Feminized Autoflowering Seeds

Q: How long to flower indoors?

7 to 8 weeks for photoperiod females. Autoflower versions finish 9 to 10 weeks from seed.

Q: How should you feed during bloom?

Reduce nitrogen at the switch. Increase phosphorus and potassium through weeks 3 to 6 of bloom. Start at half strength and raise as plants respond.

Q: Is this good for small spaces?

Yes. Compact stature fits small rooms and tents.

Q: How to prevent bud rot?

Keep relative humidity under 45% in the final two weeks. Add circulation fans and remove dense inner growth.

Q: When to harvest for max resin?

Harvest when most trichomes turn cloudy with some amber. Check pistils and trichome color using a 60x to 100x loupe.

Q: Does this strain need special training?

LST and topping improve yields. Super cropping helps dense colas if plants recover before stretch.

Q: What nutrients cause tip burn?

Excess salts and overfeeding cause tip burn. Flush with pH-balanced water and reduce feed strength.

Q: Who benefits medically?

Patients with chronic pain, sleep issues, and stress respond well to this profile.
