Revisa las dosis de nutrientes ya que no están siendo suficientes, ahora si no haz comenzado a fertilizar ya es hora de comenzar con pequeñas dosis 💪

I have not amended at all. I guess I need to start adding nitrogen? I will do more research and then start small.

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil
On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?

What are the health benefits of fresh black cannabis leaves eaten, or made into a cold brew / infusion tea that is different than green leaves?

Schwarze Spitzen und Flecken nach Neemöl-/Kaliseifenbehandlung in der Dunkelphase. Schimmel? Dran lassen oder abschneiden? Bitte um Hilfe!
November 3: At the beginning of the dark phase, I applied a mix of 200ml water with 2ml neem oil, a splash of rapeseed oil, and 4ml potassium soap to the plant. The reason for this is an infestation of whiteflies. I didn't apply everything. Today I see black spots. Is that mold?

Today I noticed 🍄mushrooms popping up with GiSCele. Does that matter? Are they🍄poisonous to girlies? Don’t bother me,but I dunno🤔. I recently started using 🦇 bat guano and have a feeling that’s what encouraged- kinda cool if I see Smurfette sunbathing on 👙🆒👍🏼

In the 3rd photo in week 12 there is spotting on the leaves. Does anyone have an idea of what that is from? A deficiency? I had trouble getting the nutrients right and that showed up first after I flushed for a few days.

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 foliage
At 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?

RunWithIt
Popped up around last week (week 4, monday). Prior to week 4, i had been watering with tap water, which in my area is pretty hard.(7.8+ pH) Been correcting pH to 6.8 with each watering since. (2 waterings since then.) Should i just continue feeding 6.8 pH water or add cal-mag?

Blackening leaves on 2 week old seedling.
Any ideas what has caused the blackening on the leaves? More effects of the overwatering? Hope it's not a lost cause but I'm losing hope.

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?
