Hey bro! 👋
You've got a powerful lamp, dude! That's cool, but it's already pretty hot in the environment, so your lamp might play a crucial role in the problems!
If the leaves are pointing their tips upwards - that's heat stress! The plant is really hot, and it's showing you that with the tips of its leaves!
Solution:
1. Raise the lamp higher or limit its power.
2. Increase the airflow in the tent.
3. Direct the fan airflow along the growing tips of the plant, but with a slight upward angle! So the fan captures the air coming from below, where it's cooler, and directs it "upwards" towards the lamp, where it's warmer and will be expelled by the exhaust fan! 👆
4. Download a free app called "luxmeter" from the app store on your smartphone, wipe the screen well, and clean it from grease and dirt. The light sensor is located on the screen part, which often rivals individual lux meters. Check the light intensity above the plant. During flowering, your girl loves light levels between 20000-100000 lux. Adjust the lamp height so it doesn't heat the plant to such shocking states, but stays above 20000 lux. Install the app, you'll remember me more than once, bro! It'll be like a compass for your lighting! 👆
Good luck, bro! ✊😇
