This plant is growing very weird the main cola is foxtailing which has caused it to go short and stumpy, lower buds are foxtailing aswell, she looks to be having some issues possibly lockout/ calmag deficiency as she is developing brown spots on fan leaves and some on sugar leaves. Will maybe flush her if it continues to get worse
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
