leaves have strange spots and yellowing

[fiona886]

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?
