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.
Blue Dream took poorly to this so I re-potted them, gave them 1-2 days to adjust and then watered them with 40ml of water.
Current end of flower plans:
01/13 - Last recharge application - Start SLF-100 only water to flush (no more recharge)
01/20 - Assess leafs to see if I need to do a quick 1-week feeding, most likely be done.
02/09 - End of Week 16 (9 of flower) - Harvest
