Hi everyone,

I'm hoping you guys can help me with this, I can't figure out what's causing this rusting and curling of the leaves on my plant. It's my first grow, just over week one into flower.

Everything was going great until about two days ago when I noticed some of the leaves were rusty, brown/beige and shriveled around the edges, this seemingly happened overnight. I have some (assumed) fungus gnats in the tent, which could be one possible cause. I also suspected potassium deficiency, I've been adding under 1ml of calmag to my water along with the nutrients. Because it's a soil grow I realised I don't need to do this. Could this be causing a potassium "lockout"? It seems some of the leaves are "dying".

Here's some pics of the problem along with pics of the new growth to compare.

* TS600 light
* Tatanka Pure CBD
* Soil/perlite
* GH Trio nutrients - (currently 2ml Micro, 1ml Gro, 2ml Bloom)
* Watering approximately every three days, or when the pot feels light @ 6.5-7ph. Intermittent plain pH'd watering.
* 15L Air pot

Thanks!

Remember pollen is airborne, can you pick off the male parts? Before they open!

first it sorry if i’m posting this on someone else’s thread idk how to do it separate but anyway is there any possible way for me to isolate one plant ( have concerns it may be turning into a hermaphrodit) that is in the same tent with a female plant without anything happening to it. i want to keep the plant growing im just trying to play it safe in case it is turning into a hermaphrodit. i just don’t have the room to grow the plant separately.

What's wrong here? Doesn't seem like anything's wrong. Make sure you check your ph when you water. You also may need more nutrients. Some bloom & flower nutrients. More light = more growth , , to an extent of course. (, but with those I doubt that will be a problem.)

Hi Haveago , are they photo or auto flower? In soil or hydro? Which nutrients? Type of light >put all this in your question, it helps people help you & we all can learn. We need some details.
Anyway, they look good for 2weeks into flower , bloom stretch happening, but looks like they have stretched extra to get the light.
Try moving light 1" closer & watch how they do.
Cut off lower fan leaves & yellow ones. If leaves yellow fast , you may have a nitrogen or magnesium deficiency , it often happens once in flower. May need to add some Cal/Mag , I sometimes use a little Epsom salts on top of soil or in water, it is magnesium.
Don't worry, they look good - nice to see plants growing in the natural Christmas tree shape without topping.
