Day 51 - Deficiencies have gotten a bit out of hand the previous few days.
Looking at the leaves I was thinking maybe calcium and magnesium deficiency, but it doesn't really make sense to me because I had:
1. Given a decent feeding with the Aptus cal-mag solution.
2. Calcium was already in the soil (pre-fertilized)
3. There is more often too much calcium in soil than too little.
4. There is a not insignificant amount of calcium in the water I use (causes limescale in a lot of things)
So my guess is instead of calcium deficiency, I'm seeing next to some magnesium deficiency, a deficiency of phosphorus.
So a couple of days ago I gave the plant FloraBloom which has both phosphorus and magnesium but no nitrogen or calcium. Today (two days later), the leaves are now feeling a lot less dry / crunchy, which was a supposed symptom of phosphorus deficiency.
I expect to need to wait about two more weeks before harvesting. Maybe around 10 days. The trichomes are still fairly glassy although there's some cloudiness. Pistils are still mainly white though, so I'm expecting some fattening to happen. I don't really like feeding the plants at this point (short before harvest), but the deficiencies were severe enough to me that I'll keep giving FloraBloom this week. Next week I might stop depending on where the trichomes are at.
Smell is excellent, I definitely now understand where the 'mandarin' name comes from. Very similar to a mandarin smell now.
Other than the phosphorus / magnesium issue, the plants seems to be doing well.
