Heavy defoliation, buds are very mature with lots of brown pistils.
I added Cal-Mag and lowered Bio Grow, the plants need calcium and magnesium in the final stage of flower, (when you see brown spots and dead tips) it helps boost flower production.
my soil is homemade, a blend of Irish peat moss and worm compost with blood, fish and bone meal, dried seaweed, chicken manure and epsom salt. Perlite is less than 5%
The week of plain water last week had no real impact, they are still very dark green, I like to lose a bit of nitrogen in flower, I may use half a dose of bio grow next feed.
