Purple is coming along and buds are continuing to develop. But Cal Mag early in the week didn't sort out the progression of yellow spots. At this stage it kinda looked like it could be early Septoria, so treated with liguid fungicide and some B.T. for good measure just in case it could be gnats.
Northern Light was just chugging along, and no photos of her for this week :-/
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*
