My plants are looking about the same height and veg wise but are at week 3. Any tips on things I can check to see why growth is stunted?

Hey man I was wondering if you could help me out I'm growing all fast buds strains, and my 2 plants that are at week 3 today are still only a few inches tall with no real noticeable growth. I'm using a coco perlite mix, using bottled water and 1/4 strength nutes. 18-6 light schedule in 5gal smart pots. My temp is around 85 during light. Please help my plants grow faster!!
