The plant continues to show signs of what I believe is a calcium deficiency, despite repeated addition of CalMag over the weeks. It may be that the plant suffered some root damage from early calcium deficiency, which combined with my too late increase in light during early veg (presumably stunting early root system development), put the plant in a perpetual shortage of calcium. When I panicked when the first sudden and extensive leaf damage appeared, I cranked up the light, fearing that I might be losing my leaves soon and hoping to generate as much energy as possible while I could. This overdriving of a plant that was already stressed has probably turned a small problem into a big one. The problem was probably further compounded by my using distilled water out of fear of high alkalinity and general mineral content of my tap water. I saw an interview with Scotty, who said that GrowDots are basically calibrated to work with calmag-buffered coco coir, so he doesn't include those nutes in the GrowDots. 'Lil sprout is receiving filtered tap water. We'll see how that works out.
I was hoping to harvest this weekend, but there are still hardly any amber trichomes, and at least 1/3 of the pistils are still very white. Buds are firm and fairly chunky. They have decent coverage of trichomes, but they're not frosty clickbait. Re-reading some of the cannabis disease literature, slow flower development is one of the signs of low calcium, so I added some CalMag and water again today. Part of the desire to harvest is wanting to get this semi-failure behind me and free up the tent for the baby WW I've sprouted, but part of it is because I'm worried that the poor health may mean that quality is dropping, rather than increasing.
Looking at the diary name, I'll hazard a guess that the plant didn't do well?
Those leaves look very far from healthy to me, although it's worth mentioning that I have little experience yet.
@tangie, I was just about to do an update. The leaves keep getting worse, but the buds aren't too bad, other than the very rusty sugar leaves. I'd hoped to harvest this weekend, but progress has been slow this week.
