Best time to water cannabis plants — morning or night?

Water when lights first come on. This gives the plant the whole light period to use the water. Watering before lights off can lead to sitting in wet soil all night, which increases risk of root rot and fungus gnats.

Started with the same setup. Worked great for my first autoflower from Royal King Seeds.

I'd add: don't overthink it. Cannabis is resilient. Start simple and learn as you go.

Good question — I struggled with this too at first. The advice above is solid.

Went through this exact scenario. Fixed it by adjusting watering schedule and it bounced back in 3 days.
