Hi everybody,
I have this problem. I was growing some giant redwood (Sequoiadendron giganteum) seedlings under some grow lights. When they got rather big I replanted them in bigger pots (used a very nutrient rich media) and brought them on the windowsill at my work. Stupid me did not though about the intense sunlight. They stood there for close to week I think and I noticed the tips not looking good. They started to seem dry and brownish somewhat. I then brought them to a shaded place, yet the tips are dying back more and more where for one of the plants it's already the whole branch.
The questions are as follows:
1. Is this really a sunburn or is it something else, like the replanting? Beside the sunburn my guesses were nutrition burn due to nutritious media or very dry air in the office I have them (although I have other plants here that are doing fine so doubtful about that).
Would like to know for the next tries if these ones do not survive.
2. Can they recover, or they are gone at this point and the damage will kill them?
I'm attaching some pictures of the branchlets and the whole plant
