Id say go ahead and harvest if you ve flushed already as you want between 60-70% of th red hairs as they will continue to ripen after chop....
DVX....I have never grown Niravana Bubbleicious but I do grow what we call Ohio which is right now still clone only and besides myself only 4 others still have it as it was from the very original mother of the original Bubblegum strain. Its only been passed a few times and I was lucky enough to get my original 2 clone cutting 10 years ago and have kept it going and just now getting round to making fem seeds out of it. Yours look very sativa heavy for Bubblegum cross as original Bubblegum has a very broad huge indica leaf. My leaves which are the mother plant leaves tend to be about 8 to 10 inches across and each finger is about 8 inches long. I harvest growing in aero at week 5 to 6 of 12/12 flower after 2 weeks veg. They will be covered in sugar crystalls almost all white with a bluish hue and orange hairs.
