quick question . clones are about 4 inches tall

i have just transplanted my clones into 15ltr pots ,& put em under a 800w lamp on 18/6 they have been in for 3 days now ,looking ok ,iv just give them only water up to now ,would it be ok to start on feed, canna A+B .......rihza ........canyzem........would it be ok ? or should i Wait a week before starting .


any help appreciated

Soon as they root
