Off schedule flowering

It’s just bag seed from someone so nothing special, I’m using Part bag soil mixed with compost, rabbit poop and chicken poop(VERY little chicken poo). Using full strength tiger bloom big buds for flowering. Can I trim any leaves off of it to increase bud production? I’ve read it’s important to leave the fan leaves on but it’s been years and I’ve seen lots of grows on here where fan leaves are removed at this stage.
