Your plants are dying from too much direct sunlight! You need to understand that at this age, the plant can't develop in direct sunlight for 10 hours a day!!!! It’s enough for it to grow in the shade (in indirect sunlight) right now! Pay attention to the lighting at different stages and measure it in the places where you leave your plant! 👆
Download a free app called "luxmeter" from the app store on your smartphone, clean your phone screen well, and remove any grease and dirt. The light sensor is located on the screen side and often rivals individual lux meters. Check the lighting in your cultivation area to ensure it’s within the lux range. Install the app, and you’ll remember me more than once, buddy! It will be like a compass for your lighting! 👆
Effective lighting ranges, starting from the planting of the plant:
Day 1 (250-500lux)
Day 2 (500-1000lux)
Day 3 (1000-2000lux)
After five pairs of leaves, full vegetation (2000-20000lux)
Flowering (20000-100000lux). Try not to exceed 99000 lux. Otherwise - problems! 👆
Good luck, friend! Take care of your girls! ✊😇
