Leafs losing Color, die off.
I could really use some help recognizing if and which deficiencies the Super Skunk has. It's currently growing in an organic soil that's been pre-fertilized and should be enough to complete the cycle. The temperatures are around 23c (73,4F) day and 19c (66F) night.

Spraying the leaves
While I was checking my plant I saw these “black stains” like the plant is “half-bitten/scorched”.Is it possible to burn my leaves and create this effect after spraying them with nutes. Blacks spots were created today after I sprayed them and there were drops on leaves for hours

Struggling with some bad soil (beginners mistake). I water with dechlorinated tap water at around ph 7.4 and 400ppm (not feeding yet). But runoff ph is 6 and around 1000 ppm. Am I dealing with a N-lockout? why such a ph difference and high TDS value?

What causes hydro Ph fluctuations early in the grow?
What causes dramatic ph fluctuations in hydro conditions so early in the grow, and how can I mitigate it? I have hard water, so I know that’s part of the issue (I tried to install a RO system recently and failed miserably). Other than frequent testing & additives, what can I do?

I'm still trying to raise my soils pH, I'm using Olympus up which has lime, should I give a higher dose or jus pH water till pH runoff goes up?
If I use nectar for the gods Olympus up which has lime in it and I'm having low soil pH probs, should I use more Olympus up and adjust my pH and would that help raise my soils pH? Or should I jus use pH water until my pH runoff is where I want it? Advice greatly appreciated.

Discoloration on leaves. Why?
I was looking at a closeup view of an overhead pic I took yesterday and noticed some slight tan/bron color along the sides of the 2 bigger leaves. I'm wondering why. Nutrient burn? Sulphur deficiency? Something else? Any thoughts?
