Mould on top of substrate
Dat_Maltez_Loudstarted grow question 4y ago
There is some sort of mould on the top of the substrate. I think I will spray it with diluted hydrogen peroxide.
Is this a good Idea?

Bud Rot? Mold? Or safeOne of the branches split during a storm the other day and didn't recover after a few days so I chopped. I'm wondering if the leaves trap moisture in the bud during the days I let it recover. The backside has a brown tint to it while the front looks green and healthy. Srry 4 pics

Slimey/Webby parts of the flower? Looks like rot or mold?I removed the infected parts of the plant and defoliated the fan leaves around the sites to help with aeration. Did she go past her prime and now she is dying? Or just because of high humidity in the air?

Schwarze Spitzen und Flecken nach Neemöl-/Kaliseifenbehandlung in der Dunkelphase. Schimmel? Dran lassen oder abschneiden? Bitte um Hilfe!November 3: At the beginning of the dark phase, I applied a mix of 200ml water with 2ml neem oil, a splash of rapeseed oil, and 4ml potassium soap to the plant. The reason for this is an infestation of whiteflies. I didn't apply everything. Today I see black spots. Is that mold?

Potential bud rot?My critical cure has some of the smaller leaves near and in the buds which are starting to turn rusty brown. Is this a starting sign of bud rot? Should I cut them early?
I do not see anything abnormal under the microscope or when separating the large buds by hand. Thanks!
