i think that you are using wrong type of nutrients
actually you should not be using any nutrients for the first monthof its life....the light that you have is good...i don't know about the soil mixture but if its well aerated and drain well then you should be fine...also it is evident that is being overwatered propably because of your excessive love to it....
use nutrients with NPK levels in which N >P<K during vegetation (but again it's not really needed, the soil is usually rich enough for a month) and change that into N<P~K when into flowering....

The leaves are turning brown from the bottom up, 2 of my plants have lost the first and second set of leaves (from the bottom up). I did some research and thought I was low on P, so I gave them some epson salt and a little bone meal to bump the P. This is the only nuts I have given the plants for they are only 18 days old. Here are some specifics: Soil: 1/2 Scotts Potting Soil .08 .12.08 Nut Levels, 1/4 Perlite, Rating: 5
