Week 6!
Day 44: 2L (PH6.3) + half-dose 4-1.5-4 + 1ml/L CalMag
Today. I learned that with half strength Bloom Feed and a dose of CalMag Pro, the PH of the solution ends up at exactly 6.3 - this means that most of my watering of last grow was too acidic because I often still added PH-
Nonetheless, while checking up on the NLA I noticed her symptoms progressing and I did what any self respecting grower would do: remove the evidence. Coincidentally, I've removed most of the damaged leaves to make checking up on her easier and to more easily figure out whether she's improving or deteriorating.
Additional thoughts: While inspecting the pictures again, I noticed that perhaps some of the damage might be a pointer towards the phosphorus toxicity theory, caused by the premature PK13-14 feed, and the additional feed of last week. That said, perhaps it's a convenience that the Pokon bloom feed does not contain that much phosphorus relatively - and since it's an organic nutrient it will not immediately raise phosphorus levels even higher.
Hence, this week will mostly be focused on monitoring her symptoms, while the buds are steadily thickening up.
Day 46: Moist, no water.
Her symptoms are progressing, I noticed that some of the leaves have a tighter gradient from green at the stem, to yellow about half way the leaf. What this means? I have no idea, I'd like to think it's a response to the fresh supply of Nitrogen from the bloom feed. However, it's just as likely that this tighter gradient went unnoticed until now.
She's got some pretty rough nute burn, so I think the best course of action is to stop feeding her entirely for now. I'm quite certain that, with the PK13-14 and the organic bloom feed, she'll have enough nutrients for the coming period.
Buds are thickening up nicely though. Her terpenes are starting to develop and I can see more and more trichomes appearing.
Day 48: 2L (6.3PH)
Her symptoms progressed even further, I'm not worried though. I removed more leaves from the lower, shaded area.
