Buds Need Beef!

Hey! Growing conditions look optimal for flowering and to be honest those buds look pretty filled in for week 5 of flower. I've got a couple of "high yielders" going now and your buds are much more developed than mine in week 5. I understand you probably expected more at this week, only thing I could think of is nutrients.. Could it be because of the nutrients? Maybe too much of a mix or the feeding order.. I read that you give them different feed of nutes on each the day, maybe something is unbalanced or is causeing her not to absrob some nutrients correctly.. Don't know, just throwing out some ideas because everything else looks great. Good luck and happy growing!
