Following the reduction of the feed schedule, I noticed a reduction of runoff PPM but that stagnated at roughly 1.5x the PPM I put in.
Also, the orange/brown necrosis I noticed last week spread a bit more and the pattern seems to suggest it is Calcium deficiency (mid level leaves, targeting the whole leaf). I started addressing the issue by increasing the CalMag I gave but still saw the discoloration spread leaving me to believe this was nutrient lockout. I decided to end the week with a reduced nutrient regiment to flush out some of that salt buildup. I'll do the same next feed and see if the runoff PPM starts to go down, if not I think I may have to do a proper flush.
For the nutrients replacement, I looked around and saw that there's a lot of documentation on using Jack's 321 in Promix HP, so I might go for that. Only problem is finding a supplier as Jacks themselves don't ship to my country.
Next week:
- Feed again at reduced PPM to eliminate salt buildup, or a flush if I see dramatic drop on plant health
- Lollipop all bud sites as I did last time (increase airflow, light propagation...)
- Eliminate all bud sites that are tiny or obstructed
