The roots are still coming out of the starter plug, im sure i could pull it out of the hydroton and take a pic, the ph was like 6.6 when I came home today I adjusted it but that was the 2nd time I've had to snd they just went in Sunday night nice and green

pH...you'll need to manage it, and right now, 6.6 is way too high for your style of grow.

Ok im checking it and adjusting daily thank you for your response

I run my RDWC setup between 5.8 and 6, I have never gone over 6 or under 5.8. Like mentioned, that’s the first thing you need to control, less water makes it harder to control so you need to be on top of it.

Ok thank you, my first run water was really stable not sure why its doing that...maybe the water splashing the hydroton? My roots are not in the water yet

I think it’s good practice to wash then soak your hydroton in ph’ed water before using.

I did and with hydrogen peroxide, I did add a little on top because it needed a little more
