Too many nutrients, its nutrient burn. Use just water in soil, or reduce feeding a good portion if in coco. Stay lit growmie.

Brown spots and yellowing leaves.
I’ve just started to get these brown spots and yellowing leaves on the top leaves of one plant. Not sure what it is, potassium or calcium deficiency. Soil ph is 6.35. Water with regular nutrients at a ph of 6.5.

Leaves curl on upper new growth and mid but not lower.
I’m using the canna coco line except boost, looks like phosphorus deficiency. I just lowered my a and b 0.7 ec and added 0.3 of pk for a total of 1.0. Is this phosphorus deficiency and do you think my changes will help. Leaves are a little dark shinny and the shape is odd.

Nitrogen toxicity?
This plant hasnt had any liquid nutes since been tranplanted 3 wks ago, i did however lightly foliar feed 0.5ml/l of bio-grow 1ml/l bio-heaven and 1ml/l cal-mag mixed with 1L spray bottle used over 1 week. My other plant looked deficient and bounced back. Could be anything else?

Brown leaves - what am I doing wrong, folks?
They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?

Rusty Leaves
3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? Doesn´t seem to be fungi, as there are no spores to rub off.

Yellow leaves
Hello, take a look at the pictures please. Leaves are turning yellow and curl. Is this a N burn, or a deficianty from some mineral? Or is this nutrient lockout? Plant does grow well!

Seedling leaves are discolored and starting to curl
Not sure what the issue is here. You can see it evolving over the past few days (Sept 29th - Oct 2nd). The leaves are discolored, light, almost yellowish in color. And one is starting to curl. There are clear images of this in the post above. What's going on here? Thank you!

Does the curl here (pic- Day 10) look like mild heat stress? Temps hover around 23-24°C (~75°F). RH ~ 65-75%. Water pH'ed to 6.5. Soil runoff tests @ 6.4-6.5. She's due for a drink tomorrow...any experts feel like throwing me a tip? Am I just overreacting?

Heat stress? (1st grow)
Hi, Here we start with the problems. The leaves are curling up (little yellow), not much. I've looked that up and it's probably heat stress? -My led lamp is at 55 cm -The plant receives 500 PPFD Also a friend told me to water it nearly 1l, if that's the case I was giving way less
