This is actual days of flowering not from light change to 12 hours. What day count does the 42 days represent? From flip or actual flowering days. The difference between the two is the transition period. The transition period is typically 10 - 14 days depending on strain and environment. A recent poster stated a plant is 18 days after flipping and sees no real signs of flowering.
These are 14 days after light change - button day
Plant looks great. Nice bud formation. You should check out @NUG61 thread on his Maui grow Maui Waui on the scrog table. Posts 1500 - 1600 cover days near harvest. The week and days used in the thread is 21 days from light switch, I believe the plants were cut, using his day count, around day 70. Adding 21 puts it at 90+ days from flip.
