hi bro , you have high humidity in tent , drop humitity under 55-60% for day and night. it is a mold that appears on the leaves when the humidity is too high and the ventilation in the tent is low. Increases ventilation and decreases humidity. π

Powdery Mildew near end of flowering
For the last few days, powdery mildew is starting to form on the leaves and some of the buds. I've cut where mildew was, lowered humidity to around 45% and increased air circulation by focusing a fan on the plant but it is still forming. Anything else I should do?

Small white spots on leaves in germination phase.
Does anybody know if those small white spots are ok? I have water 7 pH and I add some citric acid to lower it to 6 pH, when I sprinkle the soil I lightly sprinkle the leaves as well and I'm not sure if it's the effect of dry citric acid or something else. Thanks.

Too little light
I have now tried removing the WPM by smiering 40/60 milk/water on the affected areas. Deep inside the canopy aswell since little to no airflow passes here due to the plant being so deep in the pot. And apart from that the plant recieves 8 hours of light and I cant install a LED.

On my other grows I've had some issues with pests. The worst was white powdery mold, but I've also seen leaf miners, aphids etc. I want to treat this plant pre-emptively with something like BioNeem. Is it safe to do that at this stage of bloom? Can you recommend safe alternative
