Tips for bud rot prevention?

Sup friends and family! Growing 4 fem Girl Scout cookie photo plants from supreme seeds (ignore that lil guy on the bottom right in that second pic, Twas an experiment.) Outdoors obviously. This is my first photo grow and second grow overall, last year I grew 10 autos with a pretty successful yield, although I lost 1 or 2 plants to bud rot.

These plants were germinated and planted in the later weeks of May, and are just starting to show signs of flowering.

I’m growing on Long Island, New York, and we’ve had a few extended periods of rain this season, this week being almost a full week of rain/overcast. I purchased this lovely greenhouse/tent apparatus as a preventative measure, but I was (pleasantly) surprised by how big the girls got, and I definitely cannot fit all 4 plants in there as they continue to grow and start to flower. On a positive note though, it’s amazing to sit in the middle of that jungle and take it all in.

An important detail is that I’m living in an apartment where growing isn’t possible, so this is all being done at a discrete off-site location (my gracious mothers backyard, she’s become quite the grow enthusiast as well haha.) She does like to help with the watering, but I don’t want to ask much of her in the way of inspecting and treating the plants. I try my best to get there daily for feeding them or at the very least checking in on them, but some busy days I can’t get over there.

What would be the best move here? A second tent? Or just put two outside and leave two in there? The tent has 6 mesh “windows” for airflow, and I am running an oscillating fan in there to increase airflow.

I included a picture of my current nutrient regiment as they begin to enter flower. I also sprinkle diatomaceous earth on the surrounding area, and use Mammoth organic spray for bug prevention. Bugs were a huge problem on Long Island this season, so that was another added benefit of this tent.

Any advice on preventing bud rot (or any other advice if you see anything iffy,) would be GREATLY appreciated, as I feel like I’m in a bit over my head with the size of these beautiful plants haha.

Peace and love growmies!
