My longan in a pot which I put in the greenhouse about 2 months ago is starting to turn yellow and dropping some leaves. I have another one in my workshop under an LED grow light , but it is still green. I have fertilized the one in the greenhouse lightly with dynagro. Also yesterday, I gave it some dynagro in a foliar spray. It has new growth and I think I see some spikes forming.
The temp in the green house varies from 50 to 90 degrees. The temp in the workshop may be 40 to 60.
I mist each plant 2-3 times per day. The one in the green house with city water from the faucet. The one in the workshop is misted with city water from a spray bottle.
Any thoughts? Thanks in advanced. Van
I've also posted in GW but there is more detail here.
