heat,nute lock , wind burn......try 24 c temp....water only two times no nutrients .try only half dose of nutrients as on label....air flow indirect ...not at the plant... like bounced off a wall . good luck. noting the 3rd photo the leaves are "tips up" 1 and 2 have drooping leaves remember 3 if you can ..whatever you were doing just before photo 3...do that amounts/ scheduling.

Your plant is trying to conserve moisture, this happens to all ants not just weed

Hi there, Those curling leaves indicate that your plant is suffer from heat stress.Even though your temp is 28C, the space between internodes is too short, curling leaves and that heat stress causes your plant to take up more nute and becoming dark green leaves.Also check the temp near the leaves and raise your light or reduce your light intensity.Happy growing... ✌️

Hi it looks like your just on the edge of what your plants can take Ec wise, got little brown tips. The curling up is because they can't handle the heat. Give a good watering with correct ph and try and get your temps down a few deg. Knock 2 hours off your light schedule that should help and 18/6 is fine for autoflower.

Brown yellow leaves?Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.

Leaves curl, become crispy and have weird colors I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.

Cupping On the right plant in diary pic it shows slight upward cupping on the edges of a few leaves. There are a couple of others on the other side. But 95% of the leaves are fine. During my first try at LST I broke the main stem by 70%. I think this caused the cupping?

browning leaves Anybody have any idea on the cause of my leaves getting brown spots and curling at the tips? It's really just on the big mature leaves and leaves near the buds. Any smaller and younger leaves are still fine. Maybe a nutrient issue? Or is it just that its close to harvest time?

Leaf Symptom Diagnosis The leaves (pictured with weird wrinkles and crispy edges) are showing some form of stress. Theory is that they were dehydrated from the overly salty medium, but I'd love to hear from a more experienced coco grower about if and how I should intervene to alleviate the stress.

Qué podría ser? Bloqueo de nutrientes, sobre fertilización? Cómo solucionarlo?Hoy lavé raíces pensando que tuvieran un bloqueo de nutrientes. Creo no están sobre fertilizadas, pues las hojas estarían de color verde más oscuro y duras, como si fueran plásticas. Y éstas están caídas, algunas blandas y con esas puntas amarillas.

I probably have spider mites on my plant. Yesterday I sprayed it with Maag oil. Today I bought an organic product and sprayed it on the plant. Are the discolourations on the plant caused by the mites or burns due to increased light from the drops? Or a lack of nutrients?
