First i will start with some pics the I will discuss some of my concerns after I get some comments....thanks again..

Ok...here are my concerns.......the leaves are a little too bright green.....I just got my ph test and up n down liquids....

I started with full strength nutes whuich i noticed was not making my plant happy so i watered it down to less than half strength....
