First time growing DWC! Thoughts?

[pcgamer76]

DWC (one air pump -> 4 air stones)
22 gal reservoir (filled upto 20 gal below net pot)
4 LED blue/purple/red slab lights (now shown)

I began germinating these Humboldt GSC feminized seeds at 8:30pm on July 30th (damp paper towel). I transferred them to their rapid rooter homes on Aug 5th, when they had 1/2 inch tap rootz.
It’s been around 9 days now (without nutes) and this is what they look like currently. I just added 40ml - 40ml - 40ml of Flora Micro-Gro-Bloom. These are the readings I took after adding nutrients:
6.1 pH
1100 ppm
25 deg C

How am I doing?
(Ignore the little guy he’s an experiment)

1100 ppm? You are gonna fry them. You need to bring that way down

What does the feed schedule call for? I don't use the GH trio. I can't imagine it calling for bloom at this stage. Does it even call for Gro that early? What is the PPM of your source water?

Lord I never even go above 800 in flower. Go waaaaaayy down. Like see what your tap water PPM is then add maybe 75-100 ppm of grow. I just use cheap ass maxi general hydro stuff

5.7 ppm. I run DWC in the 14 gal (I think) totes

Bring nutrient temperature down under 22 Celsius
