Was sind das für Flecken?

Spewckle. Yuck.

J'ai le même problème sur ma culture du moment, je sais pas ce que sais et pas de bestioles dans la chambre. Tu utilises quel eaux ?

Definitely a pest. thrips can make marks like that, but not limited to. pyrethrine is a kill on contact option wiht a fast degredation... i'd still recommend not using it in flower. It has less than a 72hours half life if i recall... but no idea what the threshold is for 'safe'. Anything that is truly safe to apply in flower is probably also ineffective. Predator bugs are 'safe' but may need time to control it. Good thing -- definitely not powdery mildew.

When I have something similar = everything I do = it's nothing) I have never had any problems with such spots. I would say that these spots are probably constantly on my bushes. Somewhere there are more somewhere less. I'm already used to it. I do not remember the nyode occasion in my own, so that after such spots there was a bad thing. Swim like that further, I do not think that there are reasons for excitement) Maybe I don’t know something = but it's all not dangerous. Do not pay attention Refract the leaves when you know exactly why to do this. When you have a box in boxing. Do not cut the leaves without super critical reasons.

spider mite all else looks good
