Do you think its time to start feeding my plants ??

I only ask this because my plants have not yet been feed , They are 3weeks old today from cutting's , I planted into plagron growmix with perlite which is meant to keep plants feed for 3 to 4 weeks ,.
My plants have been drooping every day towards the end of the light session and then after 6 hours of night they are up and ready to go !!(i presume they are resting , as im a noob i dnt really know only from what i have read),. But to day i put the light on and they havnt recoverd , the leaves seemed to have clawed and drooped and lost abit of their colour. I took one out of a pot to check the roots they seem ok , a little dark but mostly white once again im no expert so i will post pics and let you be the judge of that one! soil looks wet , plants was watered 2 days ago ,..These plants are almost 20" in hight !

pics to follow !

Any help would be Great thankyou
