Tâches sur les feuilles qui deviennent marron

PetitGrower76started grow question 4y ago

Hello, I'm a beginner and I'm having a problem with a plant (Santa Muerte). Symptoms: spots on the leaves that are turning brown. I was thinking it might be a Calcium deficiency, does that sound correct to you? Or do you have any idea what the problem might be? Please. Thank you. Happy growing.

It does look that way. Also check run off pH. Make sure your getting good run off on feeding to rinse out old salts as well. 🌱🌱🌱

Stunted not growing Hello, I’ve been having a tough time trying to decipher what’s going with these two plants. I thought I was overwatering them so I backed off some but no change. Only given 1/4 and 1/2 doses of nutrients. Ph is been 6.3 They just seem to quit growing past couple days. Thanks

So, tiny rust spots on upper fan leaves (please see pic above-week 8). Is this a Calcium/Magnesium issue or something else? I’ve been weaning these ladies off the CalMag over the past 2 weeks and then this showed up. It’s also been very cold in my tent so I’m not sure. Anyone? 😱

Rust Spots on the leaves Rust spots on the leaves, although minimal nutes and a calibrated PH pen. All others in the same environment appear fine? I noted temps were up a little so adjusted controllers and raised the light a couple of inches, What are these spots from?

Crinkled Seedling Leaves The Sweet Amnesia Haze on Day 13 (last photo in week 2) has crinkled leaves. It’s only it’s second set of real leaves and I give it the same water I give to the other plants with the same properties. Does it look like there’s anything wrong?
