Sadly i forgot to log what it ate before and exactly how much of NPK i gave last feed but its no more then a tsp per NPK and under, i use General Hydroponics flora trio, im using tap water and have calimagic if i need, i also have hydrogaurd and when even i experience Root rot. if that dont help i use 3% hydrogen peroxide if needed, other than that, thats it. I have no clue why my thai is doing horrible, its preflowering which is fine since its my first grow ever in dwc, thanks!

When u mix the nutrients do u mix them in order as cal.ag first of u use it in the mix then add micro then grow then bloom and then mix well and pH it. pH is a huge huge factor here. If not PhD than this is most likely the reasoning it looks a little wonky. Def need to get a pH meter so pH can be adjusted before u water. Plants absorb nutrients at certain pH levels and if too far off pH it will lock the plant out from accepting any Nutrients

Exactly what @Mark0427 said, PH cannot be overlooked in hydro.
600ppm would be a good feed, working your way up to 850ppm in the next couple weeks.

Yep. I seen nothing about the pH being set before feed so that makes me think that may have been a missed step and if so that’ll do it.

I do gave a tds and ph meter but a cheap one, and i try to keep them between 5.5-6.5 ph, last feed i did not use any cal mag as i only use when needing from what i can see(im still new to this lol) so as far as deficiencies im somewhat unsure of what to look for.
I ph before i add nutes? I thought it was add nutes to base un phd tap water then once all mixed ph after? Am i doing it backwards?

No after you add everything. Then correct the ph as the final step.
With dwc you need to be checking the ph and the ppm of the water in the buckets daily to make sure it’s staying stable, you will see some shifts and you will need to correct that.
Clean out and start with fresh nutrient water every week.
