Thatās a tough one. If the plant is mutated, it often has a weaker "immune system" or internal transport system, which makes it hit a wall once the heavy energy demands of flowering kick in. Since your other plants are fine using the same routine, itās likely just bad luck with this specific seed's genetics.
Before you pull it:
Check the stems and the base of the plant for any mushiness or browning (signs of rot). If itās just yellowing quickly, it might be a severe nutrient lockout specific to its mutation, but if it's literally wilting and dying, it might be best to chop it to save your airflow and resources for the healthy ones.
If the buds still look clean and there's no mold, you could try to ride it out a bit longer, but don't let it compromise the rest of your tent!
Happy Growing, Growmie!
