Shocked stunted flowering ?

ok guys so I have a scrog going strains are blue dream, mtg B4(chemXb.dream) ,gg4(gorillaglue),xxx skunk . So Im at day 40 and my buds are looking like they are lacking in development I feel there like 10 days behind but idk .... Stunted maybe ?

My timer was on the on mode for 3days on the 2nd week of flower maybe that slowed em ??,I'm looking at my past grow journals from couple strains I've ran before, and they defenitly look a week behind

Ok so I'm narrowing it down to heavy prunning! They stopped growth around the 25th when I pruned heavily but I did so because mold prevention there were too much leaves over lapping... Anyway my plants look like they've picked up again with new pistols ... Anyone ever endure this before?

You answered your own question. Pruning.

Well there multiple things that might have caused it had the timer sitiution ,pruning, and a couple weeks of 50 degree night temps. @Alexander Supertramp .. My question now, is if anyone has came across same thing during flower "anyone ever endure this?"

Today is day 42 I noticed the growth slowed down at day 28 I noticed they slowed growth as soon as I hit day 35 with no girthness.. I was scared but for any1 that comes across stunting plants in flower . Just be patient they'll still Bounce back !!Technically I'm at 42 but I think 32 is more appropriate... So pics are day 28 ,40,42.
