First hydro grow[1000w] and ran into some issues

[seedleSs SRH]

This is my first grow and I am using as follows:

1000W MH
Fox farms 6 part nutrient system
Root 66
Hydrozyme
5 air pumps
10 air membranes
3x 18 gallon bucket
1x 5 gallon bucket
425 c.f.m blower
1x ac unit (regulate temps)
2 wall mounted oscillating air king fans
1 tower oscillating fan

Method: Deep water culture
Current light cycle: 18/6
1 1/2 week into the grow.


Im in the veg stage and I keep my PH range between 5.4-6.1. I started my ppm at about 400-450 and have recently bumped it up to 850-950 ppm range (using fox farms grow big and also using big bloom; along with some root 66 and hydrozyme). I keep my temps pretty regulated, during the light phase room temp is usually at 77-79 degrees and during the dark phase it stays at a cool 68-70 degrees.

Im not sure but I think it is Magnesium deficiency with a little iron deficiency to boot, I try to keep my ph levels within range so they don't go through nut lock. I use a milwakee ph meter and and milwakee tds meter.

I have a few pics showing the deficiency on my babies.

anyone? the plant in the back and the two on the right are fresh clones and have very little nutes in their buckets.

the ppm of my RO water is 9-13 so no worries there. my thought is that maybe because of the root complex(Root 66) their ability to uptake nutes has been increased and therefore need lees nutes?

i'm pretty lost actually. i don't know if my plants need something, or if i should be adding PH balanced fresh RO water to lower PPM

please help!

i don't know a lot about hydro, but i think Ph is supposed to be at 6.8, anymore below that is too acidic. correct me if I'm wrong though..

I will have to correct you on that. Hydro plants needs a PH balance between 5.6 and 6.2. anything higher or lower is no good. Ideal is 5.8.
