# This browning on my Thai Con started just this week… I haven’t…

_Posted by Meg 🍄🦢🌿🔆🧚🏼 on 2026-05-22_

This browning on my Thai Con started just this week… I haven’t changed up her watering. I water her once a week but USUALLY I try to go with bottom watering (is that not enough?)  
She has a grow light in front of her for 12-13 hrs a day and I just added a grow light above her again for 12 hours. She has a humidifier nearby and it’s consistently between 50-60% humidity…….

Any ideas? Is this common because of the white coloring on the leaf?

this is very very common in solid variegation. usually means too much sun is hitting the variegated part, two grow lights might be too much

She doesn’t get any direct sunlight. And she was browning before I added the second light 😞 added the second light thinking she wasn’t getting enough light for her variegation..

Does she have any time without the grow light? I think they need sleep too!

Mmh is her soil not holding on to water well enough and does she need repotting
