Taches noires sur les feuilles

Request for diagnostic confirmation: I noticed black spots at the tips of the leaves. I think it might be a phosphorus deficiency? I was a bit late in feeding my plant. In my last watering: pH 6.5 EC: 1.8 Terra bloom, green sensation, pure zym. Thanks

At week 5 in flowering I wouldn't worry to much but if you want to know what goes on for sure the you need to diagnose. Check your runoff waters ph and ec levels, and make sure their in order for the substrate you use. If ph is out up or down, that's a form of lockout. If your ec is low for your substrate then it is a deficiency. If the ec has creeped up, then you would be experiencing lockout as well..

Organic peat controlI think my plant is being eaten but gnats and it looks like nutrient damage on it but I haven’t given ANY nutrients to it. What should I do? Can you diagnose my plant? Any remedies? I heard cayenne pepper can be used for a pesticide is there other things? Does Neem oil work well?

Leafs on top turning slightly yellow and getting black spotsHi fellow growers,
any idea on what's happening to this plants?
All three pictures are different plants and it is spreading super fast. One plant in tent doesn't show any of the symptoms.
I already flushed them and gave them a light nutrient solution with PH 6,2
