Hi all!
I've been growing four Japanese Black Pines from seed over the past year and a half, but recently I left on a six month road trip and decided to (gulp) take them with me. Unfortunately they are NOT happy! They went through an initial shock (I think due to limited sun from the driving) which killed off a lot of needles and new candles. Now they're all looking pretty sad and more needles are turning brown.

I've invested in an LED grow light and am trying to keep them under it as much as possible, and whenever I stop somewhere I put them outside, but any other advice on what else I can do to try to keep these little guys alive? I am using a basic Dyna-Gro Bonsai plant food but am worried I may be over fertilizing them?

Any suggestions or advice would be welcome! Currently planning on removing all the dead needles and keeping them under the grow lights as much as possible and hoping for the best...

Those trees wil not grow indoors. Don't take trees on a road trip .
And NEVER fertilize a tree if it;s not healthy. Fertilizer is not food.

No, tell me this is some kind of joke. Very bad idea.

Why should they be happy? Do they enjoy the scenery? Plants, specially trees, don't like to be moved around.

Being very honest, I think their chance of survival, even hoping for the best, is minimal.
But... You have to try anything, right?

Trying? Right. Anything? Not really. Those lamps will make it worse if there is any chance..
