I’m thinking huge phosphorus deficiency. This is pink kush mid flower I’m trying to adjust with a runoff of about 6.5. Do you think it needs a huge dose?

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliageAt first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?

greyish leaftips and dieing branches after toppingthe highest branches died after topping. It looks to me like they had the same symptoms like some new upper branches are developing now. It looks very dark & feels soft
Temps were 17-19°C & Humidity was 90%+ Water should be PH5.9, think ph reader might be wrong and ph is too low?

Pest infestation left my plant folded and weak. I treated it, but now blacked out leaves?Ants were farming an oval shaped bug's secretions that was eating my stem and going underground, leaving a trail of a film-like substance.
Treated it with neem oil, cigarette butt tea, garlic and dishwasher soap to fend them off. Black leaves now. Tips?

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
