Need help! Yellow leaves on budsites

Hi,

Im on 8th week of flower on my high THC unknown strain, been feeding it with Gold Label Soil in the same ratio as ive been doing since 2nd week of flower;
A+B - 2ml/L
PK - 0,5ml/L
MG - 0,5ml/L
Enzyme - 0,1ml/L

Im currently seeing 20% clear and 80% cloudy trichomes.
Some of the lower leaves have slowly been turning yellow and falling off, like normal when getting close to harvest. (due to not enough Nitrogen?)
4 days ago I noticed the leaves around the budsites on the side against the light starting to turn yellow, and its been spreading, but only on the light side of the buds. What is it? It looks like Nitrogen deficiency or potassium deficiency or MG deficiency? but on the last picture it looks like a nutrient burn? Can it be nitrogen toxicity when the lower leaves are yellowing and falling off? Please help!
