HELP! Dwc leaf curl in flower

[MrMrMr]

Hay guys, im a newb.
I have a six shooter and a dark purple week 7.
2 weeks into flower.
5 gallon Dwc, viparspectra 600 and a Chinese 1000.
Gh 3 part (barely any gro) hydrogard, rhino skin silica, and botanicare cal mag at 550 ppm with tap water (200) ppm. Lights are around 18" from canopy. Water temp is steady at 74 degrees.
Room temp is 75 degrees.
Humidity 55.
Ph swings between 5.7 and 6.2.
I was using orca, mammoth p and koolbloom but I cut them.
I cut them because when I flip to flower my leaves start curling down at the tips and the flower leaves curl all the way down. And it seems they have stopped flowering.
I have an lsd-25 that had the same problem but I couldn't save it. I went to basic nutes to see if the problem could be too many microbes. The leaves also have slight discoloration. Please help these are huge autos and I really dont want to lose them. Any suggestions would really help. The last pic is the lsd I couldn't save. Oh and their water intake has slowed to a crawl, it was half a gallon a day.

I don't see anything wrong, except maybe a bit of over-feeding.

200 ppm tap water might be a problem.

"Below mentioned are some of the most common impurities found in your tap water:
Industrial Waste. Most of the impurities present in drinking water come from the industrial waste. ...
Chlorine & Fluoride.
Chlorine and Fluoride are the most common chemicals which are usually present in tap water. ...
Heavy Metals."
A cheap RO system can get rid of most of this stuff. RO buddy and PureWaterClub have cheap one.

When in doubt, cut feed, lower temp, increase humidity, and move lights further away.

@MrMrMr hey buddy.... man i hate to see this kinda thing. I have seen it a few times with dwc grows. Weird thing is everything looks good.
You got plenty of air going to the roots?

Like @Simplicio mentioned there is a slight sign of tip burn.. looks like theres plenty of N stored in her but that shouldnt be doing any real harm.

Ive been running dwc/hydro for years with 180-220ppm tap water with no problem but its what makes up that ppm that matters.

Is it possible to buy some bottled water and try a fresh res with that?
If you want to cut down on N with the flora series its actually better to lower the micro as it has more N that the grow

Good point, who knows what floating around in that 200. I'm gonna get an ro system asap. Even if that's not the problem it'll cut out any second thoughts. Thanks man.

Yeah ro system is a must now.
I'm gonna cut down on that micro as well.
Thanks man
