Ongoing brown and yellow patches forming in week 6 of flowerI'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)6y ago

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?Leaves. Color - Yellow

End of Cycle or something to be afraidHi everyone, I think the brown leaves just reflect the end of cycle (WG started flushing 4 days ago, DSD33 today).
I don't see signs of mold or something rotting, brown leaves do not detach, both plants show already some amber trichomes.
What do you think?Week 6

Are those nutrient defficiencies? Which ones?A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).Leaves. Color - Dark-brown

Is this Calcium Defic? What to do to fix?Week 9 flower. Rust spots on leaves. Starts at top. This can only be calcium defic from ALL the research I've been doing. Can anyone chime in? I foiler spray a CalMag before lights out and I've added some more to the nute mix. 6.2 pH, runoff seems good.Week 10

Brown spots on lowest leavesHallo Freunde!
Ich habe an den untersten Blättern meiner Pflanzen, Verfärbungen auf der Blattoberseite entdeckt. 😲
Ich vermute das etwas Überdüngung die Ursache ist. Week 3 Day 19
Wenn jemand die genaue Ursache und wie ich es behebe, erklären könnte?
Vielen Dank 😗
