ok.. so 3rd time grow... first time using FoxFarm soil and BB,TG,GB nute trio... and happy frog soil 400W HPS 4X4X6.5 tent...

my question is--- I am having a lot of yellowing, dying, not growing at the bottoms of a few of my plants... since this is my first time using foxfarm ocean forest soil, it states on the bag no fertilization needed for 30 days... this would (in laymans terms) be my entire vegetative cycle... I have added some of the Big Bloom and started with Grow big as I am into week 2-3 I feed once a week and water once a week and then add calmag+water if needed... I cant figure this one out.. should I not be adding anything for the first month?? maybe i dont understand the nute regime. but i started with 1/4 strength and now that i am adding Grow Big I have it at 1/2 strength... any advice would help...

pic 1 is of the biggest.. in week 3.. was just flushed.. looks bad at the bottom but has growth all through the middle... except it is small..

Pic 2 is of one that is just short and is very horizontally growing has droopy leaves but the soil is relatively dry..

Pic 3 and 4 are of the yellowing and dying i was talkign about... Nitrogen deficiency??

Pic 5 is of the youngest.. 3 wks... I dont want to give them the same fate as the others... they all show the top leaves with 5 serrated edged leaves... should I start with 1/4 strength BB? or should I just start with 1/4 BB + 1/4 GB since the BB is just a catalyst and as the bag states, it received the required nutes for the first 30 days just from the soil...
