To fix it, go to quarter strength and the extra run off should start rinsing the excess nitrogen out of potter.

Leaves roll up
Can anyone help me? I have a weirdo plant (leaves) and the others are starting to curl up. Is it too hot for them? Overwatered? Or some kind of deficiency? The lamp (Greenception gc9) is 45cm away.

Possibly nothing
Can anyone explain why my leaves are pointing inwards and facing up? Is this because its new growth and hasn't fully unravelled? Or should I change something.

Dunkle Flecken auf den Blättern.
Hey.. One of my White Widows has been getting dark spots on the leaves for days, and today I also noticed the first spots on a Blue Dream.. Can someone tell me what’s going on and how to get rid of it? Removing the affected leaves hasn’t helped.

Sick plant, nutrient toxicity?
Few leaves on my plant are beginning to burn, plant was always at least 18” away from my viparspectra xs2000 light set at 50% brightness, so I doubt it’s light burn. Temps are always 73-78 inside the grow tent, this strain apple fritter is sensitive to nutes, happy frog too hot?

I'm entering week 7, what's happening?
I'm entering week 7 from germination. I'm using a soil for herbs/lawns (pH 8) as an amendment—not ideal for cannabis. I'm testing it, but leaves look like this. I fertilize and already flushed. Using 1ml grow + 1.6ml bloom Biobizz in 500ml water (pot is 3.2L).

Over watering?
Dude, what's the problem with this girl? The transplant was done 1 week ago because the pot was small. But since then the leaves have always seemed curled and dry. Could it be above water? The top and edges of the pot are dry but around the root ball is moist.

Why are some leaves curling strangely?
Hello everyone, the problems begin unfortunately. Why are some leaves curling strangely? I have not given any nourishment, the temperature and humidity are constant, will it be a problem of PH or EC? Thank you in advance.
