Growing pretty well, started producing trichomes the other day, shes stretched to the same height as her room mates which is good as i thought she was possibly a dwarf. She has been easier to feed than the others and no signs or deficiencies or toxicity with her
Keep in mind some ambering can occur from physical damage also.. if you’re often touching and inspecting that top cola - that could be the reason for the amber color up there.
You could - or just leave it and let it go - separate the main cola from the rest of the plant when you harvest and smoke that when you crave a chill more sedate high... the more Amber cola will have more CBN and marginally less thc.
@Mr_smallGrow, yeah it started off pretty burnt, putting it down to bad batch of coco. Its new leaves are perfectly healthy hopefully it continues that way
