You can see the recent photos above from today, about 8 weeks into flowering.

Need advice on Top Bud Harvesting... have some huge nugs at the top of my canopy and I want to know if I will shock and kill my plant if I try to harvest the top nugs and let the rest mature for another 4-7 days (or more/less) while flushing

also when I do flush the plant should i use RO water or stay with my tap or doesnt matter

Doesn’t hurt mine, i use beeswax to seal the cut, Bagbalm.

I'd your plant is healthy and hardy, and has a strong immune system, you should be able to top harvest without issue and without sealing anything.
I always harvest my top buds and let my bottom/under buds further mature. Never have had an issue

How do time flushing my hydro plants and top harvesting. if I flush for 5-7 days and then harvest the top buds, will their bee enough nutrients to help the rest of my nugs mature
