Feeding EC question

So these plants have had nothing but problems since seed. I think it all started with a low PH of around 5.3 for a couple of weeks while they were in veg. I've not been able to get them looking happy. constantly dropping dead leaves. I was going to bin them. But decided to flip them let them run. They are currently getting an EC of 2.6 and have been getting this for 2 weeks now. I never go this high and am considering going higher. I dont know if thy are hungry or still suffering lockout of certain nutrients. To be honesty i still want to bin them but they are 33 days in flower now, over halfway. SHOULD I UP EC ?

I do not grow using hydroponic techniques or measurements but it is a method that fascinates me. I have to agree with @Waywardwayne that they definitely look like they are not getting enough nitrogen. It is possible that they need a bit more Potassium, too. Other than that they are looking basically healthy so it could be possible to stop the yellowing from getting worse.

What are the roots growing in? Guessing that they are in a coco coir mix.

If you had a problem with the water's pH for a couple of weeks when first starting the grow it should not matter now. It has been several more weeks of the vegetating stage and a few weeks of flowering so the pH should be OK. Unless, you just recently fixed the pH issue.

What fertilizer have you been using and what is the amounts and how often?

Do you feed to runoff every time?

he's in "smart" pots. it's a constant gravity feed system. i've always considered them dumb, it's supposed to be a lazy way to grow and it always comes with issues. every single time. we try help the growers and they always disappear when they get it running well and rarely stick around to help the next guy.

he's also in that canna a/b line that we constantly try to fix for folks.

i think a few guys got them running decent. we never hear from them so who knows lol.
i don't trust any system that sells itself as "easy". they all require attention.

edit: we see a lot of late stage problems and ph issues with them.
