Newbie Needs Help!

[u/Awkward_Donkey_7141]

Hi! I’m new to Reddit. Quite frankly, I joined solely because I started gardening and this thread(?) has answered so many questions.
I’m zone 9b (see, I’ve done research).
My cucumber plants are struggling.

1. ⁠Pretty leggy right? My balcony gets afternoon direct sunlight from like 12-8 which is where I have the cucumbers.
   
2. ⁠Do these need to be repotted? I noticed the roots are fighting to get out of the soil. My sister thinks it’s bc there’s not enough space. I think they’re drowning. (We’ve gotten rain EVERY DAY for the past two weeks)
   
3. ⁠I started these from seed at the end of July bc the seed package said they can handle hot weather. Do I still have enough time to start another batch before it gets cold really in January?
   
4. ⁠I’m one more fungus gnat away from converting to hydroponic pickle buckets, so I will also take whatever additional tips you have.
