leaves have strange spots and yellowing

how i can drop temps?

First off, the plant is VERY likely root bound,... So re-pot that sucker.

Second issue is 70-80 is closer to optimal temps during lights on. 91 is a little to hot.

Third,.. Although such high humidity during dark hours will likely slow any chance of mites. Anything over 50% risks molds, fungus and gnats. So keep it around 40-50%.

Lastly,.. It kinda looks to me like nute burn. Those lower leaves are where high nutrients will collect and burn them.

So,.. Let it dry out, then re pot. Make sure your lights out humidity stays under 50%. Don't use nutes until it recovers. Then use nutes very sparingly.

First pic is a 4 week old minutes after re pot, before recovery.

Second is the same plant a couple days later.

Vancefish i have to re-pot to bigger pot?

Aye, re pot that sucker. Once dry enough to pull the pot, do it! :thumbsup: You'll likely find roots clinging to ALL the edges of the ball. Once in the new pot, with extra grow space. It'll just take a couple days to recover and look great again.

Technically high temps just cause the plant to evaporate more water through the leaves. Thus making you water more often. However if it gets to hot it can hurt the plants. Most people just use a fan to pull in cool air.

I think your biggest issues are the tiny pot, and the excess humidity at night (Thus risking molds and such).

The yellow crispy leaves at the bottom are likely the nute burn. Just reduce nutes and water with straight water a couple times before using ANY nutes.
