I've had a problem that Ive been trying to correct for a while now to no avail. I have a Brazilian Rain tree whose leaves have been very light green (with darker veins) some are also beginning to turn yellow and fall off. I think it may be to a deficiency of some sort. I tried giving it a doses of Magnesium and Iron a few times but nothing has changed. I also tried sprinkling some trace element FRIT on the surface but that didn't seem to help either. It has been unseasonably cold so far in my area and it hadn't been placed outside until this week. I know there are a few of you out there that have a good amount of experience with this species and was hoping someone might be able to give me some answers or be able to put me on the right path as I'm beginning to get worried??
