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.

Small brown points on older top leaves1 week ago she started to get small brown points on older top leaves,and I moved her away from light to exclude light burn. Now there are a lot more of them. I flushed her 5 weeks ago, now she is getting full dosage of nutes. But these points look like nutrient deficient to me.3y ago

Nitrogen toxicity- dark leavesSeems I might have nitrogen toxicity? Growing in ffof, 38 days. I thought the dark green was a sign of health, I’m a noob. No burning or widespread yellowing tips, just dark green. What to do? I assume water the hell out of them? I assume they will recover quickly? ThanksLeaves. Other

Brown Spots, Any Ideas?Anyone know what is causing the brown spots on the leaves? So far it’s limited to one plant, and it was closest to grow light. PH of soil appears to be normal, and I have not fed any nutrients yet. The water in my house is treated with Calcite/Corosex for PH correction.Week 1

So, tiny rust spots on upper fan leaves (please see pic above-week 8). Is this a Calcium/Magnesium issue or something else? I’ve been weaning these ladies off the CalMag over the past 2 weeks and then this showed up. It’s also been very cold in my tent so I’m not sure. Anyone? 😱Week 8

Under-watering? I water all my plants equally and one seems to be growing steadily and two have stopped. How often should I be watering in smart pots and how much water should I be using each time?
Also is there anyway to save my two heat damaged plants or should I scrap them?Week 3

Lower leaves spotting helpAny idea what this could be , thought it was a calmag deficiency so I upped the calmag and added a low dose of base nutrients, plant responded next day by more spotting, I did a flush with florakleen last night and it seems to have helped I'm thinking now it was lockedWeek 2
