Greenhouse Grow 3x Blueberry Zkittlez

Were some turbulent days. The budrot spread and I had to remove more buds. I took the plant to my balcony where it's separated from the others and has more airflow. Unfortunately she got wet from the rain once and that's when I cut away some bud again. I also harvested some buds that were next to rotting ones but didn't show any symptoms so far. I am aware of mold and probably will take plant #1 to my balcony too. #2 is doing fine. I watered today on day 67. I gave 7L each with some coffee grounds. Mixture was 7 ph, water running of measured a ph of 7. Took pictures today but they turned out bad. Better pictures will follow. However here is a close up bud shot of #2 🏼 Day 68: took plant #2 also to the balcony. Around one yellow leaf on the top of the plant I noticed some brown and chopped the head off. Maybe it wasn't mold. #3 got watered with plain water ph was 7. I hope they get a little thicker before I chop 'em. #1 is little behind in terms of bud ripedness. It's still not finished producing hairs and getting denser. Pictures will follow.
