About 6 week old amnesia haze, started to show signs of slight nute burn about 10 days ago, since then I've only used pHed RO water to flush it and fed it with very weak nutes once, yet the nute burn is slowly but surely getting worse. Might this be a deficiency? I don't think it's a PH problem but I can't tell.

Well damn I hope I can get it fixed before it turns to that.
BTW I'm using ff trio with gringo rasta calmag and root farms PH down. Last time I gave it nutes was 2 ml of tiger bloom and 2 ml of big bloom in RO water.

Is that 2ml per gal or litre?
Per gallon. I was doing about 5ml per gallon but cut it down once it started showing problems
I’m surprised you’re having to use ph down. I use
trio and calmag plus and I’m in the 5.5 range in regards to ph. So I have to ph up every time. And you should be able to feed more then 2ml per gallon. I use tiger and bloom and I was feeding more then 2ml by week 6 with no burn. This is also an amnesia auto.
I’m a bit concerned on your soil ph if you’ve been ph downing the
trio. But I’m no expert by any means just my 2 cents.
You know I think my plant has actually been showing signs of calcium deficiency along with the nute burn, which would make perfect sense if the pH was to acidic. I figured since tap water was generally alkaline I'd need to pH down but maybe I was overdoing it.
Thank you!
Thank you!
The
trio will certainly drop ph. Obviously I don’t know what your tap ph is to start but I bought a cheap ph pen like 10 bucks or something. It’s a couple 1/10s off but I just account for it. Worth the small investment imo.

I think you’d being best off to get a cheap pH meter so you know that your nutes are definitely going in within a healthy range. If you can afford a better one, then do so as it will keep you on track for pH for as long as you are growing. If not, you are flying a bit blind. Best of luck!
Update: things have gotten much worse. Bottom leaves are now yellowing at a fairly rapid rate top leaves are starting to get further burned. Almost seems like I have nute burn with potassium and nitrogen deficiency at the same time.
