A Lot of vigorous growth from both girls this week. Purple Lemonade is still having leaves develop yellow spotting, but is otherwise growing well and showing her sativa side with the start of what will prove to be a pretty insane stretch (maybe 3 gal grow bags for my next run, as I think this grow is pushing the limits of my 6'5" tent height, even with the LST, unless I can find a better way to get my light hung with less dead space above it)
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*
