Brown spots with slight yellowing Hello gromies. I'm seeing some slight yellowing and brown spots on my fan leaves. I've been bottom feeding so maybe it's a lock out issue with calmag. I flushed with tap to get some run off. Any suggestions?

Upward Curling Brown Leaves/Nutrient Lock Out?I've got a serious issue. Started 3-4 days ago, right after adding nutrients and increasing light. Leaves are curling upward and browning. Not crumbling yet but look like they will be soon. Both new and old growth is being effected. Maybe the Mineralized Phosphate was too much.

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?

Brownish Spots on 2 Older Leafs. Young plant.I searched it up before posting this and what I found is: Leaf spot, canker, and fungus: Brown leaf spot, Yellow leaf spot, Cladosporium stem canker and Chaetomium fungus. Solutions I found in the comments below. What do you guys think? Can it be heat (a lot of hot days here)?

Saw this first day of 12/12 Pretty sure this is just where I got nutrient solution on my plant yesterday when watering unless it's something else? I pulled these leaves off 1 plant when lights came on this morning. Every Plant looks 💯 great besides these 3 leaves, all from 1 plant rest of plant is great.
