Day 8 Leaf comparison - What's wrong here?

[realNeat]

Shots from the Zorb, which is very difficult to hold still and focus.. There are from the lower most leaves of the most afflicted plant, where first those slick spots formed, then spread, creating discoloration and dryness and eventually curling or twisting. I do not see evidence of a mildew, but I am no expert.

It looks like a magnesium deficiency of some sort. Possibly a lockout due to pH if you have been messing around with the soils pH lately?

..... hey bud, sorry this is getting out of hand! the wasting of green leaves is weird, I'm not sure what's behind that... the white-ish spots, kinda look like a mildew,... can you get me a not-so close shot of the leaf above? Now that looks like a fungal attack, and that "wet" soggy/shiney look is pretty tell tale,.. any food safe fungicide will work, or neem oil, potassium bicarbonate,...

It's all good - a learning experience. I have more than a few fan leaf sets getting slick spotted, and then discoloring and going twisty/curly.. Growth overall hasnt stunted. Hoping to power through with defensive spells. The above leaves are long gone, cut and thrown out. I cant try getting better shots of other ones. A little bit disappointed in the clarity of the Zorb photos.

I'd spray neem oil and cut away affected leaves. Neem oil (before flowering stage) rules!

@realNeat Looks like we have the same problem brother, I have the exact same white/blotchy discoloring. Did you find out what was causing it?

@PickleRick
I finally decided it was nutrient burn from the Ocean Forest soil. It mostly affected the large fan leaf sets only and over time they super dried and curled and crumbled. I've mostly cut them away now. I still have quite a bit of mottling throughout leaves on all plants that I can only really chalk up to pH imbalances/fluctuations, which I also pin on the Ocean Forest soil. Things are going okay now though - it never really stopped growth, but one of the three plants has a lot less going on than the others.

I have had a couple plants looking like the girl on the right, first photo. Isnt that variegation? Something that AK plants can have? Atleast when i get some plants like that first leafs are very fragile and if by accident pouring water on them they get crispy, and they really dont like a strong wind or a low RH. I would say its not you, its the plant. But i could be totally wrong. If im wrong, i would like if someone correct me.
