yellow fan leaves and blooming agent. normal?

hello. my plants have been in bloom for about 4 weeks now. three weeks ago i started watering the plants with Bloom-C blooming agent. everything was going well until now. the fan leaves and larger leaves (but only these ones, the smaller leaves are normal) on one plant have started yellowing, first appearing on the bottom and the ones going up the plant started yellowing as well. in some of the threads, people have attributed this to nutrient burn or over watering. but someone told me that with a blooming agent, it turns the larger leaves yellow. is this true? if the plant is starting to go, that would be bad because the buds still need more time. does anyone know what might be going on?

hi , most plants ive grown have yellowed large fan leaves from about halfway through flowering till end somtimes the leaves just fall of, but it might also be a problem , the way i look at it is if my plants are growing and tacking on feed then there usually ok
. so if your plant is still growing and tacking on feeds as normal . i would say its ok and normal for strain to loose fan leaves, just personal opionion
maybe some else can help more
maybe post a pic or 2 that would help
