Pale yellow fan leaves

looks normal to me, nothing to worry about. Good Luck!

High musashi, I would not give the double amount of bloom nutrients because the rest of your plant looks healthy and good colour. I would defoliate the lower leaves and the lower buds (the lower 20-30%). These buds will never develop into serious buds. And then your plant can use it's nutrients and energy for the important buds and leaves. Then the amount that you give already should be enough! Happy Growing! 😋

Don't remove any leaves, they are making the energy your plant needs to grow her flowers. Less leaves = less energy being made = less growth. The lower older leaves going yellow is quite normal and not a big issue, but adding a drop of grow nutrients into your feed won't hurt. The reason they go yellow is that the plant takes "pre-made" elements like carbs, sugars, amino acids etc from the older leaves to be used for flower growing as this is more efficient than growing flowers AND making new carbs, sugars, amino acids etc at the same time - another good reason not to remove eaves unless they are completely yellow. Without those older leaves your plant has to divide its energy between flower growing and sugar/carb/amino acid making, resulting in potentially smalller flowers. With the ready made store of those elements available in the remaining older leaves, she can use all of her energy for flower growth.....

@musashi_miyamoto Hi mate its nothing to be worried about , the lowest leaves are also the oldest so they will die off naturally during flowering. A good trick to get more energy to the flowers is to remove all of the lower leaves that recieve the least amount of light doing this also allows more airflow which is always a good thing

thanks GrowingGranny! biobizz bloom is 2-7-4, so it has a bit of nitrogen. unfortunately i only have a 10-8-15 Bio ALT which just seems off. I may give her 1ml/L of bloom instead of .5, and go from there

I wouldn't worry if they're small fans leaves down at the bottom, honestly - but your nute line DOES recommend keeping BioGrow going during flower so I'd add about 1/2 strength of that to get some more nitrogen into her. Nitrogen, while seriously necessary during veg, is also needed albeit in smaller quantities during flower. Good luck!
