Need help on indoor grow

Started some Blue Mystics in Fox Farm Soil and they reached about 2-3 inches. One looks really healthy and the other one, the bottom leaves turned a little yellow. Do I need Nutes? Basically my question is when do I need to add nutes? Any advice will help.

They need practically no nutes until they are over 4-5 inches, too risky without a meter, id flush just to make sure
 
I got fox farm nute packs and started feeding and so far so good. The yellow pretty much went away and they got real bushy almost over night. I'll put some pics soon, was away for a couple days.
 
Is that odd they they're so short and bushy? Seems like they only grow out and not so much up. Wondering if I need to move the light???
