Dinafem Sour Diesel AF - Soil

Plants are looking healthy. Ph is good for both. Some defoliation - but I wonder if Cannabinoid production is produced by photosynthesis does more leaf surface area possibly help in this regard. Would love to see some research on the science behind defoliation. Leaves look almost suger coated! The morphology between both plants is more marked. The biobizz soil plant seems to show more of its sativa heritage than the other. I guess that's what happens with siblings showing that unique variation in their inherited genetics. They smell good! I wonder if they'll be ready at week 10 or I'll need to wait later. The garden compost plant buds don't seem to be swelling much more but the surrounding leaves are becoming encrusted with sparkles.
