She has yellowing and dying leaves issue for a while now. I was giving more nutes lately to combat the issue. Now burnt tips say it is to many nutes. So I decided yesterday that I should water with a bit of calmag before next feeding at beggining of the week.

Yellowing, curling tips?
I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake

Yellow and crusty leaves
Hey dear community, Why is my plant not recovering? I even adjusted the ph of the watering and add cal mag. Every week it’s getting worse and I don’t see any improvement. I use the fertilizer from Bio bizz and light is far enough away from the plant. Temp and humidity are fine

Suddenly, massive problems. Tried a lot already, nothing helped yet. Any ideas what I'm missing?
Hey guys, I've been growing for a few years now and something like this has never happened to me. Long story short, as soon as I move my plants from the veggie box into the flower box, they slowly start showing these symptoms (see pictures). The box worked fine for several grows

Did I do the right thing? Pls check my update on this week!
Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.

What’s most likely causing this?
What does this look like? Soil ph seems good and I’ve been giving them light feedings of nutrients. Any possibility it’s a symptom from being root bound? It’s just a few leaves on the bottom of the plants.

Leaf diagnosis: nutrient burn or deficiency (or both)?
he leaves with the burnt tips appear to be more prominent at the top of the canopy, only affecting new leaves. A handful of these leaves look a little twisted. Meanwhile, the yellowing leaves are more prominent in the middle of the plant, just below the canopy
