I didn’t do PH first time And give too many PPM. pH 9.0 water also. But i wanna know. Is BCTV or not If BCTV going out
Solved
Leaves. Too many
Leaves. Twisted
Leaves. Color - Yellow

Not BCTV, this is pH and nutrient stress. Watering with pH 9.0 and too many PPMs caused nutrient lockout and leaf twist. Flush lightly with pH 6.0–6.2 water and let the soil dry a bit. You’ll see new healthy growth soon no virus here

Flush is for coco or hydro, not for soil !!! Ph is MOST important thing in soil grows, its a must. I did not one grow without any food, still got result. With ph 9.0 you will poison soil very quick. Buy ph meter and ph down liquid. Those wrinkles will dissappear with new grow if you dial watering regime , humidity and temps. Not a thing to worry. Your BCTV is same impossible thing as tabaco mosaic.

1. pH 9 blocks almost all major nutrients. In soil (or All-Mix–type media), when pH is above ~7.0, most micronutrients (Fe, Mn, Zn, Cu) become chemically unavailable. So even though nutrients are present in the soil, the plant can’t absorb them. 2. High EC / PPM = salt stress. When the nutrient solution has too many dissolved salts, the osmotic pressure outside the root rises → water actually flows out of the root cells → burned or deformed leaf tissue. You see this as pale speckling, leaf curling, and slightly burned leaf tips (exactly what’s visible in your photos). Symptoms that fit this explanation Slight leaf deformation or waviness Light speckling or spots Older leaves affected firstNew growth still green and healthy This all points to a pH / nutrient shock, not a virus or pest problem. What to do now 1. Flush the substrate Use standing water adjusted to pH 6.2–6.4. Flush with about 2–3 × the pot volume (for a 13 L pot → roughly 25–35 L of water). Goal: wash out excess salts and bring the root-zone pH back to neutral. Measure the drain pH – it should settle around 6.3–6.5. 2. Then re-water lightly with a mild solutionAfter flushing: Wait 1–2 days until the soil surface starts to dry. Then feed with a light nutrient mix (¼–⅓ strength): pH: 6.2 EC: 0.6–0.9 (depending on tap water) 3. Optional: stabilize with calcium/magnesium This helps buffer the pH and prevents secondary deficiencies. 4. Observe new growth Within 3–5 days you should see flat, healthy green new leaves. The older, damaged ones won’t recover — that’s normal. Big up and keep growing ganja farmers💚😍🙏
