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.
