I recently (last week) purchased a silver philodendron along with a couple other plants. Upon arrival, they looked great, except my little silver phil. He looked a little droopy. I waited a couple of days, repotted it, and it looked worse.... Now, two days later, proper drainage, some good soil...curling leaves and dry tips. I've heard they prefer less water, so I haven't watered it again. I moved it tonight to a more central area in the house hoping maybe it was getting too much light...? Any ideas?
