Can't figure it out - plants look shitty - pics

Hi guys, I been tryin to resolve this problem I been havin but nothing seems to work. I've flushed, readjusted PH, cut back on nutes, all sorts of shit. Anyways if you got some input please let it fly, here's my info and pics.. What it boils down to is yellowing with necrotic spots developing, purple stems and buds.

Time = Week 4 Flower
Temps = 70-80 day, 65 nights
PH = Steady 5.8
TDS = 650ppm

It looks like you have a little nute burn, and a lot of times in flowering the lower fans are the first thing to start dying off. The rest of the plant looks decent to me. The purple stems are probably from low temps.

I was thinking that, but then with all the purple I thought phosphorous deficiency since there's a lot of plants sharing the same res.

yea, well, welcome to growing
seems like one problem leads to another
my experience is once you have a problem, they never look right
but they grow
and flower
and yields are probably down a little

always strive for that perfect grow, that's my new motto
