A clone that i had placed in water nearly a month ago has fairly long roots. However, they are starting to turn brown on the tips. Any idea what is happening? This clone took a long time to root, around three weeks. The roots have been growing for about a week now. A second clone that i placed in a different bottle of water with fertilizer rooted quicker, about a week, however its roots are starting to darken too. Should i plant the second one asap? And is the first one saveable at all?
They are both kept in a window where light is available. Should i shield the roots from light?
I added miracle grow liquid fertilizer to substitute for soil in both of these solutions.
