Your ph should be at 5.8 for veg 6 to 6.5 for flower. Your solution temp would be best at 62 to 68 to keep roots healthy and vigorous growth. Cheers friend

Leaves keep turning brown and yellow
It 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?

Brown spots with slight yellowing
Hello gromies. I'm seeing some slight yellowing and brown spots on my fan leaves. I've been bottom feeding so maybe it's a lock out issue with calmag. I flushed with tap to get some run off. Any suggestions?

Brownish Spots on 2 Older Leafs. Young plant.
I searched it up before posting this and what I found is: Leaf spot, canker, and fungus: Brown leaf spot, Yellow leaf spot, Cladosporium stem canker and Chaetomium fungus. Solutions I found in the comments below. What do you guys think? Can it be heat (a lot of hot days here)?

Leaves brown down the length of half the leaf
I have some leaves that have gone a bit brown down one half, but along the length. See them in Day 40 pics (I have added a extra comment there). Does anyone know what that is? I was thinking maybe it is just the bits that have been sitting under other leaves, but I am not so sure

How's the quality?
How would you rate the quality of these plants? The dark brown leaves have me self conscious of the roots situation. DIY supersoil mix recipe here: https://pastebin.com/pbxMZysq I've added more dolomite & guano as topdressing and fed liquid calmag and potassium during flowering.

Was haben meine Pflanzen?
Liebe Community, Neuling hier :) Ich habe zwei Critical Kush Auto in der 7ten Woche die seit der Blüte eine leichte Nekrose/Verfärbte Blätter haben. Leider habe ich vor 3 Tagen erst das erste mal mit Hesi Bloom gedüngt 5ml/L, vorher noch garnicht. Mehr Düngen? weniger Licht?
