aeroponic grow

Yeah, I know it's hard to tell, but what was the PH to your best guestamite?

And I certainly don't see any rot root in those pictures. The roots look nice and white. As you add nutes that will change over time so don't get freaked out about it when it happens. Especially with organic nutes. Where I thought I saw rot was where the Rapid Rooter was touching the roots the most, and I thought the stem right there looked brown and squishy. If it's not right now then don't worry about root rot. Roots look great, and they will really start bulking up soon with the new nutrients.

turns out my ph was a little high with just plain spring water, maybe slightly over 6.....it was probably even higher back when I was using those crappy nutes that came with the aerogrow. anyway, ph is now at 5.5-5.75 range (test strips are not exact, but i'm definitely in this range) which was the reading last night and then again this afternoon. I am still using the fox farm grow big at 1/3 strength. a few of the yellowed leaves crumbled off the plants and i removed one myself...everything looks good except for that one plant with the crinkled leaves (see pic) which I think is a phosphorous deficiency.

I should be getting my HID early next week...when do you think it's ok to start using it? when should i start upping the nutes?

They will be just fine at 1/3 strength, but they just might not be if you raise the amount at this point. To be as safe as possible during this recovery I would wait 3 or 4 days, then start upping it slowly if everything else looks good. (from yesterday)

And you can start using the HID right away, just keep it 3 feet back for the first day, then start moving it closer a couple inches daily while you watch for signs of heat stress. Also you don't want leaf temps to be more than 80 degrees, so keep the air around them no more than 82 degrees. This will make it hard to get the light close, so vent, and then vent some more.

water in the res looks cloudy today...anyone seen that before? I will take pictures in a little while and post...

I emptied the res today and added about a gallon of spring water with grow big at about 1/3 strength. The spots on the leaves have gotten worse (see pics) and one of the plants has very curled leaves which I think is a phosphorus deficiency (again see pics) but needless to say none of my plants are in great shape. I should have my 250 HID in the mail any day now, it's an HPS ballast with a MH conversion bulb. so here are my questions:

1) Is it possible for these plants to bounce back? or should I scrap this grow and start over once I get my HID lamp?

2) what steps would you recommend I take from here? including nute schedule and when to start using the 250w HID. I am thinking I probably want the plants to show significant improvement before I jam them under an HID..

any help/suggestions would be greatly appreciated...thanks

Go out to the store right now and get a pH up and some Muratic Acid for pH down. Get a measure spoon thats small. You need pin head drops. Get your plant to around 5.8 or 5.9 and raise it up to about 6.0 to 6.6 around week 3 or so. The plants raise pH in the soil after 8 hours and that allows the different nuets to be released because dif neuts are released at different pH in the 6.2 to 6.6 range. When there young though keep it low so it wont stress them to bad.

:rastasmoke: Happy growing man.

thanks gurilla..

here are the pics of the res: the cloudy water picture was taken today, the clear water picture is what it usually looks like..

WTF is going on? the only things I have in there are spring water, fox farm grow big at 1/3 strength, and some ph up and ph down...

anyone?

looks normal, from the nutes

The more things you add to the water, the less clear it will become. That's normal.

I would not go over 6 PH ever, unless I'm growing in dirt. Plants don't like PH fluctuations either. This can make them rebel as fast as the wrong PH can.

And where is the bubble stone or air wand? This is important believe it or not, and it will help your solution be less stagnant and therefor less cloudy.

my ph seems to have shot up..i am fluching out the res right now....i can't see the air wand....plus the water in the res looks like it's moving a lot less than it was before....oldjimmybones, you have an aerogrow, right? do you know where the air wand is? is it possible that some roots got stuck in there and circulation is not good?
