Its possible it could be nute burn. What is the ppm/EC and pH you are watering at?

Weird leaf
It seems one of my leaves has become very oddly curled up. It has very slight brown spots with a strangely curled up tip. As seen on Week3-day19. Can anyone identify some sort of problem like excess or deficiency of nutrients?

Nutrient lockout, ph imbalance or nutrient burn?
Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn. The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.

Discoloration and burnt edges on leaves
Can someone please help me diagnose this problem? At first I thought it was root dry spots from the drip watering system but it’s gotten worse. The bottom leaves are yellowing and the edges are burnt with a hole in one of the leaves. Anything helps, thanks!

They were slightly overwatered, the soil PH of 7.1 to 7.3, lacking phosphorus, maybe magnesium to. Branches from the sides are stretching, but I noticed thet lower leaves started to turn yellow a little at both. If anyone knows good advice to help them out, I would be grateful.😅

Sick Plant Help
Hey there fellow growers I need some advice. This Autoflower was really healthy up until I top dressed, I want to say it’s excess nutrients. I need to be sure though and would like some tips and help from more experienced growers (this is my first grow) thanks in advance!

What should I do from here?
I had some problems about a week ago. I investigated, and corrected at my best, but I am not sure what to do from here? Do they seem to get better? Should I do something different or just keep going as I am? - More pics and info in my diary

Harvesting a struggling plant or just letting it fight
Can she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me. Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.

Leaves yellowing and burning mid flower
Air exchange, pH, nutes, and water should be good. Could my 230 watt on 100% be too much for her? Does she need more humidity? What causes crispy leaves?

Leafs yellowing
What can this be? It happened in 1 day. Is plant asking for nuts? I added only water for 4 days because i was afraid of been giving to much nutrients. Could be a pH problem?

Plants seem to be dying after repotting
Repotted all of my plants and they are very droopy and leaves are dry. I thought they were originally over watered but now I am not sure. They all seem to be dying. Any and all help is appreciated.

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?
Everything was well, until over just a few hours they developed all kinds of symptoms. I have 2 diaries here for the grow, the 2 called “Grow #2” and I am very detailed about what has been done day to day. So please have a look and see if you know what might be happening

Yellow and crusty leaves
Hey dear community, Why is my plant not recovering? I even adjusted the ph of the watering and add cal mag. Every week it’s getting worse and I don’t see any improvement. I use the fertilizer from Bio bizz and light is far enough away from the plant. Temp and humidity are fine

Yellow/Brownish colored tips of leaves.
So, my girl now is 11 days old, while i was looking at here i noticed that the tips of the second pair of true leaves is soightly yellow/brownish colored, im worried for my plant. Could it be a wind burn ? I have a ventilator in my tent which was blowing at here. I moved it now.
