I am and ph is around 6.5 to 6.8

ok...your pH is too high.....should be about 5.8 for hydro

Ok so how do I go about changing that ? I'm going to give nutrients for the first time at 50% strength should I do that or should I continue to water with Cal mag and SuperThrive?

And I don't know if this helps but I'm 21 days in from germinating should my plant be that small ?

they do look a bit small, but no worries if you can get them back on track
