Personally I think you should of grown in soil, being your first grow. Soil as medium can provide all the nutrients needed for a successful grow, it acts as a buffer should one feel so inclined to add additional nutrients. Easier to maintain a ph range.
You can always transplant to them soil if you find it's too costly and time consuming to maintain a hydro reservoir.
Take a look for yourself... five weeks in soil, soil bought at any supermarket Black Gold potting soil, the one with the mater on it.
