Help. Leaves dry brown and spots.

daphnel · Sep 16, 2025

I have an outdoor stativa week 6 flower. Well, I flushed because of leaves with spots to start over. I reintroduced light fertilizer Epsom salt, ground eggshells, gympsum, bone meal, as top dressing fed with water soaked with banana peels and now a few leaves are turning. See pic.

Should I flush again and start over or let dry and continue with just a 2-15-15.

The terp production seems faint as well as the smell.

I am a newbie first grow. Please don’t be too hard on me. Also it doesn’t get a lot of sun because of my tree lined yard.

Hey Daphnel,
I would start by trimming some of your leaves that are turning brown. This may be due to the fact that she is in flowering phase. Have you tested your soil lately? Could be nutrient burn.

Also I was thinking upon further inspection of your leaves. What is your watering routine? Are you feeding her on a regular basis? Or when she is dry? Remember the uptake of nutes and water greatly increases as she is in flowering phase.

Trying to figure out what’s wrong with my girl beginning grower it’s my 3rd grow and trying to figure out the issue. Medium is coco buffered and all and water 2-3 times a week and temps are 73f 62rh and 1.0 vpd please help haha :)

Hey, it looks as though your temps are a little high. Do you have any fans on here? What are nutes? How many days per week are you feeding her?

Temps stay locked between 70 and 76 late veg. I have one inline in a 4x2 and one oscillating fan.
Roots organics grow and bloom and fox farm cal-mag. Feed typically once per week

I believe that your temps are too high at 76 could be way too high. Have you measured your ppm.

It does good when at 70-74 I’m in Michigan so the seasons changing is affecting the temp of the house. And ppm is 12 I use rain water out of my rain barrel this happened like over night and just can’t seem to locate either lock-out or a deficiency or toxicity due to me being novice

The strain is sherb cake idk if that strain is sensitive to the heat I’ve seen some vary strain by strain

Those leaves look as though they are reacting to too much heat. I would back off on the temps. Perhaps it’s your lights.

Maybe light burn? I’ll raise the light to 20in it’s at 18 at the moment

I've done this similar kind of damage before. I suspect a mag overload causing the brown on the leaves from the Epsom salt. If it wasn't a heavy dose, it could have reacted negatively with the other amendments or something. if you dry amended it, try dissolving it in your water instead and don't put anything else in there when you feed so as to avoid any weird reactions or lockouts.

Edit: And I'm presuming the three-fingered fans you've got growing on there is the insufficient light it's getting. Keep an eye out for "herming" on that thing, which is when a female plant grows a male pollen sac and fertilizes itself and gives you seeds... the kind you don't really want to have. Watch out for balls down below and "bananas" popping up in the middle of buds. It won't for sure happen but a plant getting insufficient light is at high risk.

Good luck with the rest of the grow and keep us posted here on this thread!

I'm going to judge by appearance, and that plant looks like the soil is too wet. That would fit for both the clawing leaves as well as tops coming in light green bordering a yellow appearance: Oxygen deficiency.

While you're not supposed to let coco dry back like soil, see if you can get a drier consistency by using less water or only watering the outer edge of the pot or something. And maybe use a moisture probe stick to tell you when it needs water. Once the roots get better oxygen it should start looking better for you!

I appreciate it maybe I’ll add another small fan lower near my fabric pot to have more circulation around the medium

Help. Leaves dry brown and spots.
