Saw today that the zipper of the tent was a bit open, can they visible reveg in only 3 nights or is it just bud grow getting bigger? And could it be that the Lemon Tree is nearly done can't find one white hair on her. Can you check trichoms
Don't worry they haven't gone into reveg. With regards to the lemon tree it looks really good but I would wait till 20% of trichomes turn amber. It is really close to being ready for harves though so check it daily. Good luck with the rest of your grow and good job
