Hi, plant newbie here...

I purchased a beautiful Orbifolia 2 weeks ago and it was looking good the first week until I moved it from a full shade outdoors position to an east window in bright indirect light (sheer curtain also).

I did spray leaf shine on it not knowing that I shouldnt have, would this be the cause for my leaf going translucent, floppy and browning around the edges? Even new leaves have died...

Since I noticed the dying new leaves I brought it back outside to its original position where it looked happy in full shade.

I have kept soil moist and watered (but let the water run out the drainage holes) twice a week. I thought maybe tap water was not good so I changed to rainwater...

I also mist occasionally but not often as I know this plant likes humidity...I've also put it on a pebble tray with low water so it doesn't sit in it... done everything I can think of but the plant is just getting worse! You can see the plant degrading and it looks horrid today...

Doesnt help that Sydney temperatures fluctuate so much from rainy and cool low 20s for a few days to hot and dry 30 degress celcius last couple days...

Hi and welcome to NGA!

From the looks of it , you keeping your soil way too wet! You want to keep the soil a bit on the dry side of moist. In my experience, Calathea doesn't like constantly wet feet. Toss the leaf shine and clean your leaves with a damp paper towel.

Plants react slowly to changes in their environment. Making sudden changes in reaction to what you have observed just now is not usually a good idea.

Given the temperature fluctuations you have outdoors, I suggest you move it inside where temps will stay consistently in the low 20's C. Indoors, it should be fine right in your east window, but open up the sheers as they block out most of the light that is usable by your plant.

Humidity is not so much of an issue as is proper watering. Twice weekly watering would be too much. Allow the top half-inch of soil to dry before watering thoroughly. Tap water is fine as long as it is not hard and loaded with mineral salts.

Give your plant a chance to adapt to its new location. Don't expect immediate improvement. In fact, already discolored leaves will remain that way. Look for healthy new growth as an indication that you are on the right course.

Thanks! I will make the above adjustments and wait! Thank you
