Struggling with Bubble Kush Auto

I've been having trouble popping seeds. This is the lone survivor of a 5 pack I've had for 3-4 years. Not sure if it's the age of the seeds or my technique... once her roots finally took hold, she started growing straight and healthy but she struggled initially. I might be seeing signs of early flowering

This girl is pretty slow but she has a rough start and I've done some defoliation and cleaning underneath

So far she looks like she's doing well. I'm not getting any leaf curling from either over watering or nutes so I'm happy with that. Just some minor leaf discoloration. I feel like she exhausted her nitrogen early.

Just waiting for her to finish. She's another one that didn't like my feeding regimen, but I'll get a decent yield I think. She's more talking almost a gallon a day. I'm giving her two more weeks max before I harvest her

I didn't get to document much as it was towards Christmas and i didn't have a lot of time. I tested her on my tCheck at 23% thc
