Hi, low grade heat stress. Nothing to worry about at the moment. Shade your pot, this will be sufficient.

Everything seems to be OK except one thing (week 3). I thought using the greenhouses at night made this, but it doesn't. When I check the plants early in the morning, their leaves are slightly curled upwards, just along the edges. As the hours go by the leaves flatten. Any clue?

Sudden Leaf Yellowing – Lighting Issue or Something Else?
Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

Dark dots in leaves. Lamp burns?
I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.

Leaves up?
Hey Guys 👍🏻 Quick question, I have my light (HPS - 250w) 40 cm above the plants - should I get the light lower? One of my babies has the leaves going up. I guess she is enjoying the light but I have doubts regarding the light distance.

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. Algunos tallos están morados.

Brown leaves - what am I doing wrong, folks?
They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?

Nute burn?
I have one plant that's browning and tips are starting to point up. I'm thinking this is due to ffof soil being too hot for this one the other 2 dont seem to have problems, though another slowed down and is getting a little twisted. Anything I should do besides continuing ph h20?
