Hello,
Someone accoriding to the pictures could help, what is going wrong?

fasbuds grapefruit Autoflower
soil is biobizz light mix
lights 320 LED
adding nutes every watering, worked way slowly to 1000 ppm last feed 2ml grow 0.5 bloom
runoff ph inbound 5,7 comming out 6,4

Maybe too many nutes - give her some plain water once in a while - biggest thing you have done wrong - haven't defoliated.

cacib , I don't dare speak on why your leaves are yellowing, but one thing I will say is that you need to thin out some of those fan leaves. Better airflow through the plant will results by thinning it out a bit.

Seems to me 5.7 ph is way too low for soil.
