Please help dwc plants are showing dark spots

2 week veg
Armor Si.
Calmag
Flora trio
Hydrogaurd
ro water at 600 ppm ph 6.0
Water temp around 69.70 . Tent temps around 75
Rh around 40
 
Armor Si. 1ml
Calmag 5ml
Flora trio micro 4ml . Grow 4ml bloom 4ml
Hydrogaurd 2ml
They came out 800 ppm so I lowers it to 600 they were doing great 2 inch growth a day then this.
And my pH pin I got 2 of them and 7.0 and 4.0 solution but one of them calibrates @ 6.86 I don't know if it matters. But they keep change. So I have been using drops.

I prefer to do a Lucas dilute modification. Some say that you can run the same ml/g from early veg to end of flower.
I follow a 1:2 ratio still, but I add ml/g according to an appropriate ppm

You have a nute lock out going on.
thats why you have those crunchy leaf tips.
drop your ph to 5.8

at 6.8ph you run the risk of floating in the 7+ range.

I know people like to run "tubs"...
I only run single 5gal. buckets. per plant.

5.5ph to 5.8ph veg.
I run select GH products, botanicare, & humboldt nutr.

I didnt like the root structure I was getting with hydroton. So I stopped using it.

Kick your ph up to 6.8 in week 4 of flower.
Goodluck.

The OP said their PH is 6

Why would they raise their PH to 6.8 in flower??

Probably root rot issue. Roots are not happy. I would personally never put anything dirty in the reservoir like hydroguard. It's a recipe for disaster without RO water.

What water source do you use? Tap/well or RO? Cheers!

I can't get the mix wright ether to strong or not strong a nuff
Tough to recover from nute lock in dwc imo try and feed on the low side especially in this early stage, 1/4 rate till about week 4 then they can start handle a heavier regimen. If your res is 15g..your probably only using about 10g so basically prep it for 2.5g. Good luck sir.
