Black spots on leaves
Black spots present on some fan leaves. During ~3rd month right now. Watering with HESI in Coco Coir, PH ~6 every time, 1/2 runoff water. For about 2 weeks prior to this, I also added very small amount of kelp powder. Soil seems fine.

Black dots on leaves ?
Late during flowering, no apparent bugs inside or anything visible. Not all the leaves, but some started drying and showing these weird black dots on it. Really not sure what this is, please help.

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?

Autos reacting to All-Mix: Slight nitrogen overload?
Pheno one showed very "leathery", weak, hanging leaves of dark green. Same time the fungus gnats had a run and the population doubled. After second LST also the stronger plant showed those signs on the younger upper leaves. Also curled down a little. Slight nitrogen toxicity?

Runoffs are significantly below inputs-Do I have a problem?
Runoff continues to be a mystery. When watering I continue to get significantly less Ph and PPM (4.8 ph and 109 ppm) than my inputs (6.2 ph and 155 ppm) but the plant looks healthy. I have no idea what is going on or if its even a problem. Should I be worried and what can I do?

Strange discoloration
The plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Grey leaf tips
Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?
