Tâches blanches

Togoutousegstarted grow question 3y ago

Hello, do you know what is happening to my little leaf? I noticed a burn so I moved the LEDs away. But I also see some white spots. Do you know what that is? Thank you!

Solved

Leaves. Edges burnt

Leaves. White powder

if the plant is damaged even in the central part as if it had signs like scratches, it could be thrips, but I deduce this from the black dots you mentioned... to see the thrips, you need to take a magnifying glass, and the black dots are their poop.... anyway, what I said doesn't relate to the photo, to me, it also looks like water spots on the leaves

@UnkleSkunk thank you very much for your response. I will keep an eye on it. I hope you're right and that it's just water! 😄

@greenAf thanks for your reply. I don't know if it's due to the watering. The pH of my water is 6.3. However, I put tap water in my humidifier. Maybe that's wrong? I've noticed that the same spots are appearing on another one of my leaves on a different plant. They both have small black dots underneath the leaves.

@Ned_Schneebly merci pour ta réponse , effectivement cela ressemble à des résidus. J'espère que ce ne sont pas des excréments. J'ai frotté un petit peu mais c'est collé je ne veut pas abîmé la feuille 😟

In that photo it just looks like residue left from water or somthing, can it be washed off?
