9 times out of 10 this is due to lack of Calcium.

There's no doubt in my mind that this is a Calcium Deficiency, which can easily be fixed with a dose of Cal-Mag, but the damaged leaves aren't going to get better so you might want to remove them.

Brown Spots on Leaves
I’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

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.

Browning of leaves, heat burn or pests?
Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.

Deficiency?
Non riesco a capire se è una carenza o una bruciatura da luce, secondo voi? Cosa potrebbe essere ? Appare soprattutto sulle foglie a ventaglio....

Leaves keep turning brown and yellow
It all begann with what I thought was light burn. I then considered it CalMag deficiency. Giving it CalMag did not stop it. My current guess is too low pH due to strip inaccuracies, so I gave it around 8 today instead. What do you recon, why could it keep getting worse?

Leaves looking f’d?
What’s happening with these leaves? It started last week and has spread. Only the leaves in the middle under the light. Week five of flower. Was using the same nutes and strengths since flowering started at 6ph. Upped the strength this week to see if it would fix and it got worse

Continuing calmag deficiency
What I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciated
