really confused about PPM

Since switching to RO filtered water i am quite confused

the dutch pro chart says 250-350ml of A + B per 100l
0.1ml of cal mag per L
0.4ml of silicia per L

this in my RO water is 500ppm
EC 1.05

i'm with very long vegged plants just on day1 12 12 first bloom feed
i was just following the bottle in veg 1ml per litre of cal mag and silicia
almost doubled up on everything to reach 800-900ppm and just ended up with deficiencys as soon as i included the cal mag i guess from too much extra cal

i'm reading i need high PPM and 1.8EC for my stage and big plants
how?
should i just double up on the A+B? keep adding until at 1000ppm?

Do u mean with everything mixex your feed is only ec1.05?

Typically with RO water you need more like 5 ml per gallon of calmag. What calmag are you using? Lets see some pics of the deficiency.

It's not letting me post pictures I think my phone has too many mp

Oh there they are

I know this is my first hydro grow but looked amazing until a couple of weeks ago then I brought a lumatek zeus pro, installed RO filter, brought some cal mag and silica, cleaned the system and everything went tits up
Think I'm just gonna have to deal with it, so many changes at once I have no idea
Even if someone was to say for example I need more nitrogen what? How? More A than B? Or closer to that PH number I dont get it, these hundreds of problems I've had do not happen in coco

Hey I'm on the DutchPro site now basically says (0.1) to 1ml per liter on the Calmag. Just stick to 1ml per L as that's the same feed chart for general hydroponics, basically 5ml per gallon. By looking at your photos, and if you're already feeding calmag at this 1ml per L rate, I'd lean more towards a nitrogen deficiency. With calcium issues the leaves will look rusty color and yellowing leaves from the inner part usually is nitrogen. I've also seen other threads here pointing to potassium deficiency when yellow starts from the outer parts of the leaves but try some REVIVE by advanced nutrients or REPAIR by CYCO either at 1/5 dose hope that helps. I'd also avoid doubling up on the A+B feed, it might cause more damage/nutrient lockout. Less is usually better with hydro can always feed more later.

I suspect the roots have issues. Good chance you have root rot.

Is that a soccer net
