No new growth in 5 days should I be worried?

I bought clones the other day and I've had them for about 5 days. They are about 4 inches tall. They have virtually no new growth but they don't look unhealthy. My friend told me this is because they are adapting to their new environment and they have to root into the rockwool cubes. I'm growing indoors hydro set up with rockwool cubes. I am hand watering them once a day with very small amount of nutes (300ppm). Should I be worried? Here are some pics. Thanks.

If they arnt showing signs of death I wouldnt worry yet... No leaves turning yellow, brown, burnt, etc. transplanting, especially with clones as in the have to regrow their roots, if your in hydro you should be able to pull it out a bit and see if the roots have started coming out yet, assuming they have just started being day 5 as it usually takes 3-5 days... update us.

Thanks a lot. IS this what everyone else thinks too?

yah I'de agree with ru8fru be patient and GooD LucK

looks to be too warm and/or too humid.

no nutes til you got roots!!!! the clone/s should not grow until they root, and should not be fed until they start growing. just superthrive and water.

my clones take weeks to start rooting so if yours hasnt then it probably wont grow for a while still. Not sure if they need any nutes yet

Do not pull on them!!! Do not feed them yet. I also think that you are over-watering, you want those leafs to reach for the light.

Good luck with your grow, my clones took a good 3 weeks before the roots grew to the bottom of my net-pot.

Don't use any nutes until the roots have shown visible growth!
