You have a moderate S def going on here. Ignore me; if you have already addressed the issue.
Add 1 tsp/gal of Epson salt bump to your weekly feeding regiment. It would be a helpful boost.
Additionally, after watering, I’d add in 1 tbs ES, to be topped around the meristem. This 1x (possibly 2x) dose, should raise levels outta def. Do this additional mound to each plant with the woody stalks, climbing up the green. Some advice for you to take or leave.
Potash (potassium sulfate)
*Natural S (aka brimstone)
Beware of the last option. I don’t usually recommend its use; except for, highly experienced growers.
*There’s no specific dosing guide for the use. If over used, it will tank your soil pH for months. It slowly begins reducing pH over 3 mos, and then it begins to incrementally reverse for 3 mos. Imagine it like a bell curve.
But, please, never hesitate to give your opinions on/in my journals, your advice is always appreciated and worth it’s weight in gold, imo. Even if I can’t always act on them, the knowledge is stored in my brain for some future reference.
