Not enough leaves on that thing to perform enough cellular respiration if you did, the stages for "new growth" is gone, all she can do is refine what is already made, yyour buds looks fairly even all across the plants so I would'nt bother, all you would really look for if you did is ripening the lower trichomes a little longer to get that 10% amber if the top buds managed to get a little overcooked through accelerating degredation of THC to CBN via high light/heat, trichomes on loweer buds could use a extra week, no problem, thats down to your judgement and your trichome cloudiness, Just dont expect a second spurt of magic growth, doesnt quite work like that.
