Either looks like nutrient burn or light burn. What nutrients are you using?. How far away or your lights and what power do you hav it on?

Too much N - glossy and dark. That may be interfering with other things, as you have more than just this symptom. May want to correct that first before tackling other issues just in case it is the cause of other visible symtoms (lockout potentially)

Mein aktuelles Tagebuch zur Pflanze ist auf meine Profil. Ich habe nun seit ein paar Tagen an neuen Blattspitzen leicht verbrannte Anzeichen und bei manchen Blättern hängen die Spitzen sogar runter. Ich kann eigentlich sagen es ist keine Überwässerung oder Nährstoffüberflutung.

VPD related leaf issue? Brown spots, don't think its Cal related. Pls, any help would be appreicated.
Brown spots on leaves, I thought it was Cal related, and tried different doses, with no success. Could it be VPD related? It can and does get very hot and very humid in the 1.5ftx2.5ft closet. Even when running no humidifier (Live in AZ). I've been struggling with this for months

What to do with crispy curly fan leaves that do have some resin on them?, I'm already on flushing.
Some fan leaves are starting to look a bit too crispy and curly, they do have some trichomes, I'm 3-4 days into flushing. I'm not sure if the dry matter can "contaminate" the buds somehow, and don't know if I should do something about it, I'm planning to get some "bubble hash"

Magnesium or Nutrient Burn or?
Magnesium deficiency, or nutrient burn or??? Only on the lower leaves so far, curling down was existing genetics - but the burnt tips are new and some have even curled up now. Probably 5+ weeks left so too early for natural dying off?

I have a problem identifying the cause.I notice that the lower leaves become dry, crunchy lose their color. But only the very last leaves at the bottom. I do not notice any problem towards the apex. Does anyone have a lead please? An excess of P ?or K?

Forbidden runtz excess or deficiency problems autoflower
BAD WEEK! need some help here guys.. Brown / rust spots started to appear on the tips and slowly started yellowing leaves. Im following the master advanced nutrients chart and watering 2 times a week. Last week feed was 20 litres R/O water 80ml bloom A 80ml bloom B 40ml of every additive on the chart 20ml cal meg 30ml phup PH adjusted 6.50 After i started noticing the brown spots / leaves curlin up and stunted growth i skipped a feed and flushed with plain R/O water used 30 litres for 4 auto plants. Yesterday i watered again but cut the nutes in half. 20 litres R/O water 40ml bloom A 40ml bloom B 20ml of every additive on the chart 20ml cal meg 20ml phup PH adjusted 6.50 I still don't know what the problem is, if it is a excess of something or a deficiency..Looks like a cal meg deficiency but ive beed using cal meg since the beginning. Maybe i have excess nutes in the soil and resulted in nutrients lockout of cal meg or something else? since i water twice weekly should i water with nutes always ? The master advanced nutrients chart still sometimes confuses me. Please any help will be appreciated

Suspected nitrogen toxicity?
Does anybody have any insight and suggestions for what's going on with plants 2 and 3? I'm treating them for suspected nitrogen toxicity, feeding them calmag-only water. Their runoff EC is still 800-1100 though, which is below influent EC.

Your opinion?
Today flushing the wedding cake i was thinking that the problem was an excess of nutrients, but instead water was quite clean, around 1100ppm at the first drain, after several flushes water is now on 600ppm. I also raised the lights.. I still do not understand 🤔
