4" PVC Single-Res Aero Shuttle (in progress)

Thanks Earl. I think I may end up aving issues with roots in my res.... the roots are already in there and I've got a long way to go.
We may have a problem. I initially thought the plants were suffering from nute burn although my PPM has never been over 470. I think I have some sort of deficiency and considering that this is my first hydro grow, I'm not sure what it may be. I've taken some good pictures of the condition and would appreciate any feedback on a fix.
I actually recalibrated my ph meter this morning and it was off. It should have read 4.0 when submerged in the 4.0 solution but it read 4.5 so I fixed that.
I think my ph was too low and it has caused a deficiency.
I do not think this is nute burn. For the last 4 days I've ran them at 300 PPM.
This condition is on all plants.

.......wow, thought by now you'd have all kinds of answers. I wish I had them for you..... Your meter definately made a difference......so I would lean to defs too, or lock-out........ The nute always sounded low to me, but I know that Earl KNOWS what he's talking about and knows your nutes....
Hope things get better for you quick-- I am usre they will--all else seems perfect!

Room temp = 70*
Res temp = 66*
change res every 7th day
PH = 5.9
PPM = 500 (1/2 Sensigrow A & 1/2 Sensi grow B)
I just foliar fed them 1/2 Teaspoon of garden lime per quart of water as instructed for a calcium deficiency.

I have had the same symptoms.
I think it is from the roots being in the rez
when you make pH adjustments
and changes to the nute load.
This happens to my plants in the space shuttle.
Only the plants with roots in the rez.
the other plants weren't affected
until they grew roots long enough to reach the rez.
In the 4 inch aero unit
I lifted the roots and put them into the tube
and they were trained to grow there.
I didn't have this problem in the 4 inch system
because I kept the roots from growing into the rez.
It is probly not too late to stuff the roots into the tubes.
You just need to make sure the tubes are draining well
after the roots fill them at the drain end.
I calilbrate my pH meter
every time I mix a new batch of nutes.
5.9 seems a little high and will inhibit the uptake of calcium.
AN recommends between 5.5 and 5.8
so I use 5.65-5.75
I would use a product like Botanicare Cal-Mag Plus
to add calcium if you need it.
Not lime.
I think the lime will lock out soluble calcium
without bacteria to break it down.
We don't want to have any bacteria in out aero systems.
There is no benefit
and some negatives.(smell, cloggs, etc.)

Thanks for the great post. The roots are back in the tubes and have been since we talked last. I have ordered some calMag.
Thanks for all you've done for me. I hope this scrog makes you proud in the end.
just took a picture of the canopy. As a longtime soil grower I am amazed at how fast these plants have grown. Here's the breakdown:
Clones were cut and placed on May 4th
The first roots sprouted on May 10th
Today is the 23rd day since they have shown roots and they are already in the net which is 14 inches above the pipes.
I know that my picture updates will be pretty boring until I flip the lights and show you guys some serious bud porn. However, I dug 2 holes today so I'm gonna mix in a little outdoor project here too.... This will also be my first attempt at growing outdoors. I'll place the plants in a few days and be sure to take my camera along.
I've consulted with Soniq, Irie, Earl, and a few other experienced guys on various sites and I've adjusted my ph after calibrating my meter along with a nice lime bath(foliar). Thanks to everyone that had input. I think they are already looking better.
room temp- 70
res temp- 66
PH- 5.7
PPM- 500
Overall I am really happy with the way my first attempt at Aero/Hydro is going and I think they look pretty good even with a touch of calcium lockout.

Those roots look completely amazing in there like that!! Those look like some real stout stalks already as well.
I can imagine the relief you must feel that the issues have been straightened out and rapid progress is back in gear. Right on!!
Dont forget to bring your camera when you head out in the bush!!<---that'll be cool!

Earl,
I am almost convinced that the root(no pun intended) of our lockout problem was due to the roots laying in the res. Once again you bailed me out....lol
I'll never be able to thank you enough for the knowledge you've passed to me. Someday it would be really cool to smoke with you.
I'm just over the hill you know.
Thanks again for helping me.
Will do man. It's been raining here for 2 solid days so I havent been able to go to my spot. Hopefully I'll get out there tomorrow(camera in hand).
Rain stopped. When the sun shines I'll go plant the girls. This is going to be a 1 man-2 plant deal. I won't invest much energy into this. I have 2 - 18 inch mothers that I'm going to plant..... I hope they make it because the extra yield would be nice..... they are 18 inches tall now and will have 2 months to veg before starting to flower...... I'm guessing they could reach 4 to 6 feet If they make it,.............. which would be great!
The spot is owned by a timber company...they log it and then leave it sit...they owns THOUSANDS of acres in the area. There is no ATV travel and very little hunting pressure. Perfect spot.......
