In a semi organic grow, would you use Advanced Nutrients Flawless finish when the plants are ready, i have been using Bat Guano and GHE Ripen -

Looks good to me, those problems go away if you go hydro

Used advanced for years cut out cal mag and bud candy just use the flawless nothing else. Use flawless once then just water. Lots of air flow keep humidity from building. Good luck

I’m not familiar with the products you mentioned. But those discolored leaves from the center of a fat bud, like yours, makes me worry about mold/bud rot. Early signs of bud rot are discolored leaves coming from the buds. I would gently open up the bud at the location where those leaves are coming from and take a look to make sure they are still healthy. I hope so🤞
