Problems with a few plants flowering

[DrDankness]

Hey guys. I have 20 plants in coco that are about 2 weeks into flower(not counting first week). 15 of them have tiny buds but 5 look like they are preflowering but no buds like the others. They are all on the same table and get the same everything. I have Purple Bud, Blueberry and Gelat.OG but there are 17 Purple Bud plants and 3 of the others. The BB and Gel dont seem to have buds but some of the PBs dont either, so its not strain based i dont think. Ive never had this issue before. They are on 12/12 light, fed 3 times a day and the temps are 73-75 during with lights on and 68 with lights off. Anyone know what could be going on?? Sorry about shit pictures, phones camera is garbage.

I’ve grown plants 12/12 from seed and it takes like 6-8 weeks to even show signs of flower that way.
So I think you got nothing to be worried about. Some trains take longer to flower.
Just give her more time. Plants grow at plant speed.
the phrase watching grass grow ring a bell lol.

Well the issue is that other plants around them that are the same strain are flowering hard and these arent. They are all 8 week strains and some have full on buds and some just look like they are preflowering

Same strains different phenotypes. If they are hybrids there all kinda going to be slightly different from each other.
