Now we're more or less current, and this is as close to an "on-time" entry as I've made for this diary so far. I did a big tent cleaning and reorganization to give these girls a bit more headroom, and replaced the old plastic standoff shelf with AC Infinity watering trays (used as just overflow for now). It seems likely that I was giving too little water on previous waterings in order to try to avoid having rampant water on the bottom of my tent, which may have contributed to what I expect Purple Lemonade's primary struggle has been (see the following). But both plants are developing their trichomes and terps nicely, and smell glorious. Northern Light has some robust buds, and Purple Lemonade is doing pretty well too, if less dense. Likely she'd have denser buds if I did a better job pruning bud sites, but I simply didn't have the time to stay on top of it.
Purple Lemonade: No matter what I try to do or how I try to address it, she seems to want to put out spots on her leaves. I've looked at ph, pests, fungus, nutes... At this point, it seems like probably some on-going low grade nutrient burn is most likely (those spots never developed into septoria as it tends to look in the late stage with blackening spots), and maybe I should have just hard flushed her weeks ago, but at this stage she's going to be going on just water for a couple weeks anyway, and then once her trichomes look about ready, I'll hit her with Fox Farm Sledgehammer a few days before she gets harvested. But I think not watering to a good overflow has maybe caused uneven spots in nutrient concentration and thus ph in the soil, and I think she's just perhaps less forgiving than Northern Light. Hopefully the AC Infinity trays will help all that with future grows.
Hey! This looks like leaf septoria (here's more info about it: https://www.royalqueenseeds.com/blog-leaf-septoria-yellow-leaf-spot-on-cannabis-plants-n678)
I'd recommend removing the infected leaves and controlling humidity (<40%) 🙌🏼
@James, well, I followed septoria guidance as well as possible. That is to say I removed all the potentially affected leaves on Northern Light, though Purple Lemonade would have been left with no foliage if I had done so for her, so I just removed the worst looking leaves. Still, gave the whole tent a thorough dry-out period. Northern Light has been pretty happy, and Purple Lemonade never started dropping foliage, so maybe she’s just a much hungrier girl than I gave her credit for and this was a CalMag thing. Or, as my partner has suspected from the start, just a bit of a sickly seed. *shrug*
