My plants are yellowing at the bottom

I've been flowering for almost two weeks and since I've noticed that the bottom branches are dying. I have 6 plants under 600w hps. I water every other day. And my nutes at this time are 0-10-0. Does anyone know what I'm doing wrong?

Magnesium or nitrogen deficiency? Missing something in the nutes 0-10-0 is no nitrogen at all.
 
N N make plants Lush and Green.. is your plant Lush and Green? 0 -10 -0 Why ever would you use that... If you want to be easy use 10-10-10.. But you need N from start to death. More N is Veg LESS BUT NOT ZERO N in flower. I dont like to pick up dead yellow leaves, So I give my plant what it needes to grow.

I would try to get some complete fert, something equal like 8-8-8 or 12-12-12 to help get the plant on track.
 
Normally I would have used tiger bloom 2-8-4 but the guy at the hydro store told me to use the 0-10-0 instead, I've only grown once before. I guess that's my fault. So I need to find something that's equal or cal mag? Do I trim these dead branches. Next time will the tiger bloom do the job?

You could use it now I wouldn't go full strength though, and yes some cal/mag
 
I haven't been able to take a pic but if anyone is still able to help me I finally was able to get ahold of some CaMag and I got some Floraduo A/B for my nutes. My plant is already yellowing severely. Is there any coming back for me? Ill post pics soon.
 
use tiger bloom and grow big and big bloom according to schedule... dont just use tiger bloom. theres a reason you feed grow big a few times during flowering. also always add cal mag at the start of flowering.
 
Do you think my crop will be okay? I'm no longer using tiger bloom because I couldn't find big bloom. Instead I'm using Floraduo A/B by General Hydro and CaMag.
