I have said plant in my aquarium tank under 16 hours of light. This plant has been struggling all year since I listened to an article instead of my sense. I have a ton of new growth and some flowers. But the older larger leaves are turning yellow an brown in the cource of one day. The death is very minimal given how much growth I have but I did read that this type of leaf Loss could be due to a lack of magnesium and Iron, the source of this information is the Gulfstream TropicalBonsai Journal. I just want to hear from some people that actually grow these plants.
On an unrelated note the weather in Michgan has been horrible. 4 inches of rain followed by a hard free. I did manage to juggle the plants around some I had to remove from underwater. I think I saved as many as my health will allow. I will admit I am impressed how the artificial lighting is doing. I will be buying lights for the side of the tank to cover the bottom part of the tree.
Question 2 would be tropicals to fertilize or not? Searching online only yielded conflicting information. Some people say fertilize year round some stated to not fertilize in winter under lights. But given how much growth I have seen under these lighs my gut tells me fertilization should continue, perhaps lower the frquencyof fertilization by say half. Any thoughts? My soil mix is very fast draining and low in biomatterso to me it seems like a very reasonable decision to add fertililize.
Q3. If plants are in an unheated garage if the temp drops too low is a heating mat under the tree a valid choice?
