Massive screwup of a week.
The plant was entirely stunted during this week and my pH pen (which has not been calibrated in 3 years) broke.
After buying / calibrating a new pen, I realized my pH level was 7.5ish this entire time.
I adjusted the pH down to 6.5 using citric acid and ended up flushing the plants, the Sluricane is drying out.
Current end of flower plans:
01/29 - Start of Week 15 (8 of flower) - Start SLF-100 only water to flush (no more recharge)
02/09 - End of Week 16 (9 of flower) - Harvest
