It’s leaf septoria. A fungus.
Remove all infected leaves ASAP, Make sure to keep the ground under your plant clean.

You really need to know what he ppm is and what the ph is doing hydro. Get the ph drops to double check your ph meter.

Plant looks like its P deficient.

This didnt just happen overnight, you're just now noticing it. Get a proper ppm meter, maybe get a different nute line,

if you use r/o water you should be using cal/mag to stabilize the ph.

I changed my res last Sunday before that my plants were just fine. I carefully observe my plants everyday day but since I change my res that’s when spots started occurring it’s been a week n this is the results. My oh is always 5.8 -6.2. I only let it drift up to get intake all it’s nutes. I’m not sure the exact ppl but it’s only a tad bit over how much nutes I put in my last res. My floor are cleaned wit h202 also put in my res every 4 days. I do recall adding cal mag to my last res so maybe that’s the problem.

You need a ppm meter.

I do recall adding cal mag to my last res so maybe that’s the problem. NOPE. unless you added a shit ton cuz you dont have a ppm meter to measure how much you are actually feeding it.

h2o2 can burn fine root hairs fyi

You cant use RO water without cal-mag. Your better off just using tap water if you dont add cal-mag to RO water. What your seeing is a micro nute deficiency from not adding any cal-mag to your rez. Tap water already has these nutes in, where as RO completely gets rid of them. You should empty your rez and fill it like this RO > Cal-mag > silicate > Part A > Part B > Ph down

Also instead of silicayi use h202 is that ok. Someone just recently said that it burns new roots
