Crispy dry leaves


#1

Need some advice why this plant leaves are so dry and crispy on the top section. It’s not too close to the light and my nutrients I use is stable. My others are doing fine but just the one plant

First what lights are you running ? Even if your lights are not close they can still burn your plant if they are intense strong lights . But take the back of your hand and place at the very top of your plant canopy and if it’s warm on the back of your hand from the lights , it’s almost double the heat to the plant and can cause this or heat stress ?

I agree with @yoshi, no matter the lights it is possible to heat stress them use a laser temp gun to get temps at the canopy level, or use the back or your hand of its to hot for you its to hot for them.

Blow this chart up if it’s to do with nutrients this will help
