I recently got this silver dragon. It has been under a grow light for about 12-14 hours a day and about a week after I got it, I repotted (into bigger pot as it was root bound) it into a chunky soil mix with perlite and orchid bark. Ever since the repot, the leaves got mushy and started drooping with these spots. Seems like an overwatering issue, but wanting to rule out a possible light issue or pest issue?
