BC Backyard 2.0

Was looking at the pictures can't really tell but it seems like may just be preflowers. Either way, I would leave it alone, she'll be fine with the increased light time. Worst case ontario there is a bit of flower growth and when she goes outside and gets back into veg it will branch like crazy from bud sites, just have to thin them out a bit (or not depending on how bushy and dense the foliage is) and you'll be just fine.
