Anyone know what is happening to my miniature rose? When I got it (pic included), it had nice dark green leaves, and has since put on a lot of new growth and new blooms. I had it under a grow light and think I might have sunburned it a bit, but it just lost a ton of leaves, all of which have yellow veins or are crinkly. Does it need fertilizer? Is it going dormant? Any advice on how to help it is appreciated, or if this is normal let me know!
