Day 31: 2L (PH6.3) with 1ml/L PK13-14
She's definitely well on her way to stretch, and some of the bud sites are already showing signs of consolidation and an increase of mass, not so much as to call it stacking or bulking, but a great early flower nonetheless.
To aid with bud forming, I've started mixing in some flower nutes. I'm starting at half dose and will probably follow up with a regular watering later this week.
Additionally, after taking the pictures, I removed the upper fan leaves of the main cola and the next highest too since it was outpacing the others. I'm trying to not agitate her too much to prevent stunting.
Since she's grown so much, the main cola was receiving 900 PPFD, and the lowest canopy budsite - in the front on the pictures - was receiving about 450 PPFD. Hence, I raised the light up to 30cm above the main cola. I haven't remeasured the PPFD afterwards.
Day 34: 2L (6.5PH) + 0.5mL/L CalMag
