Are you feeding with calmag ? What are your room temp and RH ? Led ? We need more info to help you, but it looks like you can easily fix by adding calmag. Also they look like you are wagering a bit over needed, or mb to much ppfd, i say this from the way your leafs are curving and shaping them selfs. Any way growers love and hit me if i can be of any help 💚💚💚😇😇😇 happy holidays buddy and happy growing 💚💚💚

It could be from the leaf resting on your grow medium. Or you medium has run out of nutrition and needs some adding to it. Good luck

2 out of 5 plants are showing signs of nutrient burn? Soil growHi, I am seeing clear signs of nutrient burn but only on 2 out of 5 plants. I feed them organic nutrients, following the chart that was provided by BioBizz.
Why are they still showing burned leaves? I watered them thoroughly until the runoff was clear. But leaves keep burning.😦

Brown rust spots on oldest leavesBrown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?

Leaves keep turning brown and yellowIt 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?

Deficiency on Fem. Girl Scout Cookies?I am watering sporadically and only every 2nd watering I add nutrients... haven't checked PH in a while but is usually around 6.5
The top leaves have no burnt tips - so am I (finally) having a nutrient deficiency?

Continuing calmag deficiencyWhat 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

Personally I think it's the hydrogen peroxide 12% mix, the hydrogen gave one of its atoms to the neuron of the Diatomaceous earth metal clay. With help from heat

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

brown spots sugar leavesI've asked this before, but the issue still seems to be there though it's very minor. Some of my more developed buds sugar leaves are showing brown markings. Last watering I flushed her but the markings seem to be spreading still, although very slowly. What am I dealing with?

Amateur braucht HilfeMy Blue Cheese Auto isn't doing so great...
In my opinion, it shows signs of clawing and root rot, I need tips.
It's in a 19L pot, I know it's a bit big.
I have clay pebbles at the bottom and then mixed coco with all mix and let it grow in coco on top.

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?
