The micronutrients ARE important but your plant wont die or suffer much without an abundance of them. But it was probably too early to nute them already how big are they right now? i dont start nutes until the 5th or sixth week because i dont want to fry my plant. but anyway, for vegging you'd probably want the 28-7-6 at a much lower dose than recommended and if i were you wait a few days/waterings and watch for any nute burn. and if you do decide to use the higher one make sure you dont use it for at least a week or two because your plant is still pretty young
