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

[Supportradicalhabits]

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.

Plants too small, ppm too high.

what ppm do you reccomend?

[disrupt86]

A general guideline for TDS levels is as follows: seedlings = 50-150 ppm; unrooted clones = 100-350 ppm; small plants = 400-800 ppm; large plants = 900-1800 ppm; last week of flowering = taper off to plain water.
this is just a general guide.you need to take into account your waters current ppm before you ad anything.my ppm in my town is horrible.its a solid 600 and a beotch to work with.hope this helps a little

well i'm @ the upper end for small plants. these are all rooted clones, the big one has like 30+ roots and atleast 15 of them are 2 ft long!

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!

Reverse-Osmosis water is NOT good for plants, (it has all the minerals removed) ... your plants need the calcium, magnesium, iron, etc., or you WILL have problems ... either find different water sources, or add 10ml of Cal-Mag+ to each gallon of RO water ... let tapwater stand overnite, and see how it tests, it may be OK to use ... :smokin:

cool thanks for the advice but our ppm of our tap is 800-900. sucks. picked up a gallon of cal-mag+ so hopefully this fixes my problem
