question about ferts

hello,
i'm a very new grower with some very new grower questions....;)
someone explain to me that only n,p,k , the main food for plants, are salts. he said secondery elements and trace elemnts are not salts and can be applied in full strength from the begining since their not salts and cannot harm the little seedling. i'm kinda sceptic about this but wanted to make sure with you growers.
allso , english wise , when you say ferts you mean n,p,k and all the othrs are nutrients ? did i get it all wrong ?
any ways , i feed my seedlings with only water and good soil mix for now and it looks o.k so far.
thank you and best to all.
eezee.

You don't need to feed your plants nutrients until they have 3 internodes, the 2 little round leafs that form first have enough stored in them until that time. And as far as what your buddy is telling you don't even pay attention right now. Just go and buy nutrients from a hydro store and do what the back tells you as far as amounts per gallon or what the guy at the hydro store recommends. Learn how to grow first, what your buddy is telling you be it true or not is of no concern to you now.:thumbsup:
