Re-potting

Hi there im thinking of re-potting my lil plants now because the roots have started coming out of the rooting cubes, i bought some biocanna rhizotonic and it says on the back to use when re-potting but im not sure if my plants are too young to give any form of nutes. Its only around 5-7 days old and around 2".
Any help much appreciated, Happy Growing

Usually no nutrients until 3rd week.

cheerz .

Has long has the plant has roots showing this is normaly the time to add a small ammount of nutrients.If it says add 4ml to a adult plant then add around 2 ml.Make sure not to get any water with nutrients in on your plant this could cause nutrients burns.

since yesterday, but can only see bout 2-4 lil roots poking out each plant. i decided to give them some biocanna rhizotonic at 1/4 strengh (1ml prl litre)
