Seedlings

My seedlings are about 15-20 days old, and have (in general) 2-3 leaf sets. Yesterday i noticed the tips of the leaves were turning yellow / burning and curling up. No nutes or anything except water has been used. I haven't transplanted from my seedling cups...using flourescent tube lights. any help is appreciated.

Not rockwool, just little cups i used to start my seeds. Basic starter soil. store bought. nothing fancy. maybe it has nutes in it already? i don't really know what kind of soil it is--i got it at lowe's or home depot

you really need to pay attention to what you are buying @ the store could be rat poision for all u know..IMO..
