Weed doctors to the rescueDay 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏1y ago

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 😗

Unknown rust on 7th flowering weekThis started as what I thought was a cal/mag deficiency, bought some, gave it for a week at a good dose and 6.3ph, and this intensified and switched from just lower leaves to the upper and a few sugar leaves on one plant. Any ideas? May calmag takes awhile? Or wrong diagnosis?Leaves. Color - Dark-brown
