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.

What is causing this Leaf discolouration overnight after a lot of tent work yesterday
Spent a lot of time in the tent yesterday. Everything was fine and this morning there’s bad discolouration on the leaves of some plants. I did lower the plant (was way too high) so may beight burn - but it’s only on some plants I did make two mixes of water/nutes

Phosphorus def in veg?
Phosphorus deficiency in wk 4 of veg? I noticed a few small discolored blotches on lower leaves 2 days ago and today it is a lot worse! Use flora trio, and 2 other plants in this run are under same conditions with same nutes. Could this be a pH issue? PH has been consistently ~6.

Carencia de Mg
Flag-shaped leaves with yellow spots, no doubt a deficiency of Mg. The problem is that I don't know what causes it. I will do a soil acidity test to be sure, but I'm leaving the thread open for more experienced growers in case they could lend me a hand with this.

Flushing don't seem to solve my lockout
It's been 6 days since I noticed the problem. first thought it was a deficiency but really is a lockout. I flushed 2 days ago but she keeps getting worse. Am I being impatient? I flushed with tap water pH 6-7 until the runoff was in the same range and haven't fed her for 4 day.

Check out my week 7 update for more info. Only one plant in the tent affected so it's really bugging me?!? Thought it was overwatering. Left them 2 days between feeds and they are bone dry and pots are light. Any suggestions or could it just be a trait of the Pheno?

One of the plants doesn't look so good, looks like is related Cal/Mag deficiency but I added it after 10 days from seed so not sure if I had to add more or is something else. Any clue about it?

Is this a disease caused by a lack of calcium and magnesium?
I pruned these problematic leaves during the flowering period, wondering whether this would lead to a decrease in yield. Calcium and magnesium were added every time I applied fertilizer. What caused the disease? Overnutrition burn?

Possible P Deficiency?
Hey everyone, hope all is well. I noticed these past few days some dark spots appearing on some of my higher leaves. From what I’ve read it looks like it could be a Phosphorus deficiency. Any ideas? It’s on two out of three plants of the same strain. All same feeding schedule.

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)
I have 2 plants in the tent and one of the plants is showing quite a few deficiencies. Many leaves are now yellow with brown spots. The other plant doesn't have these deficiencies, both were watered the same, etc. A few days ago, I used dolomite lime and worm castings.

Brown spots/yellow tips after accidentally breaking a blade
Hi! I accidentally broke an older blade from one of her leaves, and after a couple of days that leaf started getting brownish spots and slightly yellowing tips. Is this normal to happen after a broken blade and will eventually die off? Or is this any sort of deficiency? Thanks !

Ongoing brown and yellow patches forming in week 6 of flower
I've also noticed today a couple leaves looked wet, so tried to wipe it off but that did nothing. I took 2 pictures of the same leaf at slightly different angles to see the shine. It's only the skunk effected (closed similar question prematurely in skunks diary)

N or P deficiency?
Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

I’m seeing brown on the lower leaves. They also appear particularly shiny like a magnolia leaf. Is this too much iron or magnesium?
