I have the co2 coming on 2 hours before the light actually and my ph is actually low at like 6
Is there a chance you can measure the pH before CO2 is on and after it turns on? Most go for a 1 point pH drop. Also, how long have you had this tank set up? Aqua-soil can run out of nutrients, and the ferts dosed in the water column may not be enough after all the nutrients are used up. Yellowing in plants are usually (but not always limited to) nitrate deficiencies.

My nitrate is steady at 20 ppm , and I ordered a phosphate tester Hopefuly I get it soon so I can test that also
Keep us posted.. If your phosphate levels are fine, your potassium levels should theoretically be fine as well since you're using an AIO fertilizer. In that case it may correspond with CO2 levels due to plant growth and mass increasing

This is the phosphate result

Seems like your phosphates are definitely low. Phosphate deficiency can definitely be a big possibility since you're running co2 and co2 increases plants' nutrient uptake.. I would try to get kh2po4 dry ferts (or get a premade phosphate fertilizer) and dose atleast 0.25-1ppm and maintain it there. After a couple weeks they should bounce back in health.

EDIT: Also think about dosing EI. This rules out any plant deficiency possibilities as you're dosing in excess. It will also be cheaper in the long run (and initially, I think). Providing your CO2 and lights are tuned in (and from how beautiful your tank is, I don't doubt it) you shouldn't get any crazy algae as they'll always be in competition with your plant mass.
