Browning leaves sections of leaf surface discoloured
GreenLivingstarted grow question 4y ago
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!

It is nothing, don't worry and it is not a deficiency, it is most likely a bit of staining from splashing nutrients on that leaf.
Besides, no plant will ever have 100% perfect leaves, 100% of the time!

Do these look healthy? Thoughts? I'm new to hydro/growingI have autos growing in a dwc system being fed half the regular amount of hydroguard, calmag, and grow/bloom. 1 plant is a week younger. The dark green plant looks like its leaves are clawing and has big brown spots on the leaves. The other has some brown dots and little yellow.Leaves. Curl down

Was haben meine Pflanzen?Liebe Community,
Neuling hier :)
Ich habe zwei Critical Kush Auto in der 7ten Woche die seit der Blüte eine leichte Nekrose/Verfärbte Blätter haben.
Leider habe ich vor 3 Tagen erst das erste mal mit Hesi Bloom gedüngt 5ml/L, vorher noch garnicht.

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!Leaves. Curl down

Calcium deficiencyI already had a question a week ago, now it's easier to see, camera still bad.
But here are some fan leaves which I believe are showing a calcium deficiency.
Calmag is in the post, just waiting for it.
Is it for sure a calcium deficiency only? Thoughts?Leaves. Color - Dark-brown

First time growing/Need help in late flowerOver the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?Leaves. Curl up

Yellow bottom leaves/brown spots on bottom leavesHi guys,
So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her?
Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else?
Besides this, the general condition of the plant is good.
