recirculating hydroponics

I’m on my 3rd grow in ebb and flow recirculating style hydro. I took my rooted clones from my aero cloner and transplanted into hydroton. As soon as I transplant, yellowing occurs. My ph fluctuates from 5.5-6.2 and my ppm with the .5 scale is 725. I need help! I have no idea what I’m doing...

Hello everyone! I have tried dwc twice before and lost both do to root rot, I would like to possibly run a small reservoir to keep it outside of my tent and away from the lights. Has anyone made a small one or two tote setup? What sealant and fitting would work better for hdx totes?

My new growth on Wi-Fi is sagging, the rest of the plant looks fine,I am running a 6 plant recirculating hydroponic system! PLEASE HELP!! Pic included
