DEAD Brown patches?

Ne body know?.......have a guess?

i had the same issue, was heat issues or hot spots as they call it. but not from the usual cause of water droplets evapping, but from my reflectors not being mylar and maintaining heat as well as lumens.

OK i have another problem that i think the experts will be able to help me with. Sorry i dont have pics this time but my 5 week old is starting to show me dime sized brown patches that are causing the leaf to die. could it be that i am overwatering. Also the patches start small and get bigger starting at the middle of the fan leaf.
new growth is fine.​

What kind of lights do you have? some light, if water gets on your plant the light will intensify and burn your plant.

It also could be a pest problem, look at the under side of your leaves for any sign of bugs, or holes on the underside of your leaves from bugs.

It sounds to me like bugs, try spraying some 7-dust around the area of your plants, DO NOT get any of it on your plants however lol.

Anyways if you was over watering it, the whole plant would be droopy so to speak.
