Hi guys,

Got these 6 criticals in my rdwc system and they're now for a good week in and showing some leaf signs. One plant has brown-ish spots and others some blue-ish on the edges and some yellow tip colours.
Anybody here van help me identify what this could be?
I only added tapwater (280ppm) and pH 5,8 and yesterday put just a little bit calmag to it.

How big are the plants

Ppm in tap is misc garbage, fish guts, and who knows....lol

In DWC always start with 1/4 strength nutes
Get a pH pen and ppm pen,test yer water

My tap is like 600ppm, I see rocks falling out of it ..lol

And read read read...then read some more

Also get an enzyme cleaner like hydroguard or z7, z9 in Kanuckistan

They're only 7-1/2 days till they saw light, ppm in rdwc is now around 300's with only just a little calmag added and pH is 5,8.

HAhahahahaha
Sorry 7-1/2 days
Water ppm without additionals is around 275ppm
Nutes: General Hydroponics flora trio, Botanicare Hydroguard/silicablast/Cal-Mag, Great white, Humboldts Golden Tree, Advanced nutrients voodoo juice.

Ppm is irrelevant if you go 1/4 strength nutes as I mentioned

Do it, check ppm, move forward

I don't go by ppm, I just measure to determine if my plants are eating nutes in the DWC or not

I go by strength. I max at about 1/2 strength base nutes, full strength on additives.
Then I always know what I'm running at
