forgot the setup:
soil: Light Mix Biobizz
Light: 190W LED distance about 60cm to top
Strain: Auto/week 4 (Bruce banner 3)
Temp/Hum: 22-25C / 50%
Light: 190W LED distance 50cm to top /24h
Feed: RO water with cal/mag till 90 ppm then grow food till 400ppm ph: 6,5 /
last runoff: 800ppm ph: 6.0 so immediately gave her 7,5 a few sips on top, because my guess is that the pH is to low, the drop off was at 6,3 which if i am right is desirable.
