High density of foliage, sweat, high heat, humidity and most prob small lack of potassium... My guess.

Looks like water that dried on leaf. Unless it is all over I would not worry if this is only leaf like this.

Why the twisting/wrinkled leaves?
Why are the leaves curling/wrinkling/twisting? The plant seems healthy over all, about 9 inches tall/4 weeks old. It looks as if the leaves are too close together causing it to wrinkle, but that also doesn't seem like a correct guess.

Spots on leaves
Any idea what these whitish yellow spots are? They appeared overnight. I'm growing in ffof with perlite and ewc. No nutes added yet, just bush doctor cal mag at half dose 3 days ago with great white, recharge, and photosynthesis Plus which was the last watering of 1.2 liters.

Yellow tips on most leaves. 1 gallon yesterday, no nutes (every other water) at a ph of 6.5. just did her stretch. Otherwise, looks good and healthy. Lifted the lights up just in case, but I want to stay ahead of this. Any thoughts or recommendations?

I have gone overboard with Nutrients. Soil PH went down to 4.5. Flushed soil and PH back up to 6.5 - 7. Getting some brown splotches on both plants but only on the older "first" fan leaves. Wondering if that is just light burn. Plant is much happier now. Backing off Nutes :)

First time using Coco (Canna Prof), since seedlings the leaves are deformed and exhibit over-watering symptoms. In 3.5L pots with white healthy roots showing from below. Water (with nutrients) every 2-3 days. Could someone suggest where my problem focus should be?

Pointy Leaves
Extreme nub here. I look at other grows and it seems my plant has sharp point on leaves. Is it the genetics or am I doing something I shouldn't? The plant is doing great growing looks good to me but I see the leaves seem pointy . The plant is auto Northern light in soil.

Brown Spots on Leafs
Thanks guys, must be the break as it flowered early too... I also noticed some brown spots on both plants, some leafs . Worried it's mold but it wipes off with moisture and I've been misting with molasses water. Staining from too much molasses in the mister maybe?
