Is she DeaD ??

Looks like nute burn, maybe heat stress? Combination of both perhaps

Ph ou racone trop serré ou alors trop d eau résultat ta plante ne peut plus se nourrir arrose à l eau ph ajusté 2 jour puis tu reprend avec 600ppm engrais

High WalterWhyte, NO SHE IS NOT DEATH SHE NEEDS HELP NOW!!! This is a phosphorus deficiency in a very late stage! You need to act now!!! The cause of this dificiency could be pH issues or nutrient lockout due overfeeding. You can measure the pH from your soil to make sure that this is not the cause. I will explain how to do this. And if the pH is in the right range then you need to flush your soil so you can start giving the right amount of nutrients again after the flushing. I will explain you how to flush the soil after I explained you how to measure pH in soil. To measure pH in soil, just follow these steps. Your pH should be around 6.2. 1. Place soil sample about ¾ full in sample jar and add distilled water to cover soil. 2. Cap the jar and shake the soil vigorously a few times. 3. Let mixture stand 10 minutes to dissolve the salts in the soil. 4. Place the pH tester into the wet soil slurry. 5. Measure pH and record measurement. If the pH is in the right range then flush out the nutrients with a good flush of your soil. For this flush just follow these steps: You can do this flushing by slowly pour water pH 6.2 onto the top of the soil, allowing it to drain freely from the bottom of the pot. Pour slowly, so the water doesn't overflow from the top of the pot. Use approximately four times the pot's volume in water to flush the soil. For example, use 1 gallon of water for a 1 quart pot. After the flushing you need to let the soil (almost) dry out completely. From there you can start giving water with pH 6.2 and nutrients but do not exceed EC 1.5 Goodluck! 😋

Get some more circulation in there and maybe move your light. It looks like it is getting hit by heat stress and drying out leaves that are already in the process of being shed due to low light. If you haven't lollipopped and defoliated, I suggest you do so. I hope this helps.

What lights are you running? Looks like it’s not getting adequate light 🤔 but could be anything, like GrowingGrannie said if you do a more detailed diary it would rule a few things out. Good luck 🌱

No, of course she's not dead... she still has green leaves which only means she's alive! But she IS suffering... a diary would help us help YOU to pinpoint the reason and suggest things you could do/not do to get her back to full health. Good luck...
