Help with hydro!!

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 wrong. I’m feeding General hydro with 6ml per gallon grow, 4ml per gallon micro and 2 ml per gallon bloom

Are you using RO water? It looks like magnesium deficiency. Are you using any calmag?

I’m using RO water and I have used cal mag

My ppms are going down and the ph is rising so I know they are drinking the nutes

How many mil per gallon are you using of calmag?

About 1ml per gallon.. every time I increase it higher than that I get little black spots on leaves.. almost reminds me of how a banana develops spotting

Wow thats weird. I run r/o also and use 5 to 7 ml a gal. I use the botanicare line of nutrients.

This is what it looks like when I add more
