are my roots big enough-advice needed

i started a cheesewreck seedling in some rockwool then a week later i bought an oxypot to experiment with a bit of hydro after a good spurt of growing the roots look like they are calming down or just not growin as fast do u think the roots are healthy an will a ec of 05 be strong enough for the size of baby

Looking nice, If you want a growth spurt in your roots add a little Superthrive to your feed, An EC of 0.5 sounds good, Whats your tap water EC? Give it maybe a week and up it to 0.6EC or 0.7.

my tap water ec is about 01 and ph is about 7 ish after ive left it over night. i was givin them 03 now 05 so 07 is about right yeah and should i be using rhizotionic

should i refill water back up 2 the net pot or stay at ten litres any help

Buy some AN voodoo juice. Its expensive but results are unparalleled and a little bit goes a long way..def worth the investment. Another good root product is called Great White Shark, its made by Plant Success..stuff works great.
