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.

Cal-Mag and N Deficiency in Flower? Thanks!
I'm guessing the yellowing and brown spots (in Wk 8 pics) are related to Cal/Mag and maybe a lack of N? Would love some advice from someone who's seen this before Thanks! I'm seeing this in all my grows to some degree- using FF trio and FFOF but not for much longer

Leaves turn brown all of a sudden
What could these brown parts mean? They show up randomly, also on lower leaves, so couldn’t be the light being too close? Thanks!

The last few days I had 3 plants start not looking so hot. The 3 pictures are the 3 plants when I got home today. I haven't really encountered deficiencies, if it's even that. I'm watering at 5.8 and last I checked the runoff a 2 days ago it was 6.8. Any ideas?

Hojas marrones
Hola soy nuevo, quería saber cual es el motivo de estas hojas amarillas marrones que tengo . Soy novato es mi tercer cultivo , podría ser quizás sobrefertilizacion , falta de algún nutriente o algún bicho? Envio fotos de las hojas afectadas y la planta en general.

Spots on leaves and little twisted...
Spots started slowly showing when it had a different 600w light, too much heat back then, this started a little "save operation" changed light, made the plants look a bit healthier but now it looks like the spots have spread and also affected the leaves above... Are they healthy?

Weird burn
Thought I had a calcium deficiency but now I’m not so sure. Could have got a bit too much direct sun out of the tent. Any ideas on this ?

K deficiency? Or something else?
Not sure how to go about this deficiency. PH is solid at 6.5 so it’s not a ph issue. It seemed I had corrected the deficiency when it first appeared a few weeks ago, but now the brown spots seem to be spreading again. I think it might be K but not sure? Any ideas?

Should I harvest early? Light stress, leaves browned and dried out, buds are all amber pistils
So this plant has been suffering from light stress for the past two weeks or so. I have removed all the dry and brown leaves. The buds still seem fine-ish. Should I just give her the chop early and save what I can? She's been flowering for some 6 weeks.

Brown spots and yellowing
What do you think this is? Nutrients deficiency or maybe soil ph. Happened overnight and the plants are a little dry but I just gave them water and nutrients. My ph tester has been broken so I’ve sorta been winging it with some ph strips.

What is this brown spot?
What is this brown spot? 18” from light. Just fed about 10 hours ago with dr.Earth 1-1-1 liquid solution watered in with 1/4 gallon of water. It is the only spot on whole plant. I know the temps are high. Wondering if it could be something else.
