White Rhino Dwc Issues

I'm having serious issues with my white rhino. I transplanted it last Thursday to dwc. I sterilized everything. I didn't want to start another thread to junk up rollitup but Noone would help in my grow thread. I'm using tap water but it comes out the tap at 26-30 ppm. The ph hasn't moved but from 5.8 to 5.9. I'm using humboldt 3 part nutes. I'm running it at 460ppm. Is this not enough or too much?

here is another pic of it. The bottom leaves are yellowing and the new growth has burnt tips and slight yellowing on the edges??

I would say up the nutes a little. It seems like a mg/cal deficiency..... what's the temp of water? How many air stones you have in it?

Hell yea. Thanks bro. I have a 5" airstone. I'm not positive on temp but room temp doesn't get above 78 or below 68

anymore advice would be much appreciated. My rhino is still whithering away. I upped the nutes to 680 ppm last Thursday and the yellowing on older fan leaves continue. Upped my Cal and mg and it still going on ???

So much help here. Glad it was a fuckn male
