At this age/size baby plants need baby feeding. Giving them 8 different nutrients won't make them grow faster. Just give them "grow" and "micro" and all will be fine until they are more advanced, say 8-10 nodes, before increasing feeding. Half strength until then is probably plenty strong enough. Remember, it is a lot easier to correct a slight under feeding than it is to rescue a over fed and burnt plant. The leaves will never be 100% perfect, 100% of the time, ever, and you are probably seeing the first indications of nutrient overload. Hope this helps,..
