D34 - yellow buds Help please

Hello appears to be a fungus. lots of water and lots of humidity. Try lowering the humidity and letting the plant dry out, cutting off infected leaves and praying for the best. Also be careful with the space between the plant and the light. Good luck.

To much nutes and burnt to death with your light.

It says you're giving 37 ml/gal of nutrients, I'm not sure exactly what you're giving but 37 ml/gal of anything seems way to much. Your leaves are dark green, curling, and plastic looking so at the very least you probably have a nitrogen toxicity but without knowing the exact products you're feeding with, could be other toxicity going on. I would water with plain water, no nutes and see if conditions improve. When you start feeding again, start at lower doses.

AGree overfed.

Burned from being waaaaaaaaay over fed.

No, it started way earlier. Thats already a huge problem. Simplified - overfeeding. Stop giving any nutes for 2 weeks. Watch ph and make sure you have wet/dry regime.

Guess its no genetic, since its only day 34 Whats your humidity level? Looks damn wet, the air and soil. I doubt its 60% RH looks more like 70%+ Your leaves and bud looks like they are partly rotting, some leaves i see completly black/brown. Cant tell if its mushy since its a bad quality. But you growing area has to be way drier, its not a jungleplant.
