The leaves on the upper plant wake up today with a brownish spot. It’s not light burning for sure (ts 1000 dimmer 70% height 50-60cm). Feeding problems? The first two photos are dark brown, the last one is yellowish.

Browning leaves sections of leaf surface discoloured
Day 18 leaf worries, browning areas, slightly metallic shine. I think from reading it might possibly be a phosphorus deficiency but I’m not certain so though I’d ask for advice. Thank you for your time and all answers are appreciated. Have a great day!

Small brown spots on certain leaves
Some leaves are showing small brown spots. Around 5% leaves affected and all are close to each other. Can this be an infection? Otherwise plant looks healthy

I have no idea what these brown spots are on my seedling?
Brown/ rusty looking spots on seedling. Only thing I did was spray with a Epson salt and B52 foliar spray. The soil is deprived of magnesium so that’s why. I think I corrected by using cal mag. The sister plant is a few weeks ahead and showing recovery.

Look like Zinc and Calcium deficiency? Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC) Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.

Fertilizer burn or something else?
Hey fam. Plant seemed fine a few days ago besides a mag deficiency. Decided to foliar spray cal mag at half strength a few times. Now there are brown patches and leaves/stems are curling down like they’ve been overwatered. Too much cal mag? Burn? Something else? Thanks!
