Hydro seedling help

Can some one please give me some advice, i have a dwc setup, (1st hydro grow) so i germinated my seeds (red cherry berry fems) the paper towel way in ph 7 tap water.

I then soaked rockwool in ph 5 water,my seeds went in and sprouted,but i watered them in ph 7 tap water while they was in rokwool,they all have tiny spikey leaves on but arent growing fast, they are about 4 days old out of seed.

Should i have used ph'ed water throughout my grow and if so shud it be 5.5ph.

Help please, we were all hydro noobs once!

Make sure you arent watering them to much, they dont need a lot when they are small.

Should have used ph5.5-5.8 water but yours will probably be okay. Start using ph'ed water now.
