New leaves coming in yellow

nevermind to the previous question, my shop has them in stock.

so what would you say the optimal EC or ppm should be for my nute solution?

I would go with the oxygen solution and try lowering pH (but keep a close eye on it).

As SKH says - your pH is fine, your PPM is fine everything looks good - we are running out of options!

ok that was my biggest concern was the temp.

where i live its been pretty mild, but got wicked cold really quickly and the temp in the room which the aero is in, has been only about 73. it was at 77 before.

my res temp has been at 68 degrees. i didnt have the therm in there the past weekend because my buddy borrowed it for his hydro setup. so im sure the res. has gone down too but i dont have a reading yet.

could the temp be the big factor here?


so if i want it around 560- what the best way to up that ppm? I guess i can get by with the TDS meter until i get that mutli that emails recommended.

so to up ppm should i add more nutes or what?

well the air stone will go in tonight.

keep on this thread!! ill get back to you the results of the air stone later this week and im going to post those other pics.

i might tinker with the ph later this week, for now im going to focus on 02

yes to up the ppm, you'll want to add more nutes... but, it might just be the oxygen problem.

Also your res' temps are perfect at 68f... you couldn't get it better.

Gotta be the oxygen problem.

yep - temps are perfect!

well again, i really appreciate the help

i put up the post on my lunch break when i checked on the plants and the inital response was pretty low. i was hoping to get a couple people like you folks to hop on

i found a "make your own" type bubblewand airstone. theres a lot going on in the rest with the 'root bars" which are just plastic bars the roots are supposed to hang over, and then the pump is right in the middle. i think that will give me the best design for this particular res.

ok here are the pics. my digi got thrashed somehow so im taking them with my phone.

the first one is of the holes that you put the seed cups in. you can see a little chute and thats where the water circulates and drips down into the cup.

the second is a pic of the cup, the grey thing is the foam "medium" that holds the plant in place.

the last pic is of the cup sitting in the actual aerogarden, you can see the roots and the large thing behind it is the pump. i know back in the right it looks like dark brown roots, but that is just residual soil that i couldnt wash off in the transplant.

*****some of the roots do look kind of beige, not as white as the others. could this be our problem??

the res is only about 4" deep at the deepest point.

and to go back , emails, to what we said before, the CFLS are exactly 4" above the tallest plant

heading out to grab the airstone...

got the airstone.

on the front of the aerogarden there is a little door to check the water level, top off. etc.

it doesnt stay shut with the air tube coming out, so i just ran the tube thru an empty hopper, so no light can enter the resovoir and everything closes normal

ill give an update in a couple days, lets you know how these things are doing

the first pic is the hose coming out of the hopper and the 2nd is the glorious 02 bubbles flooding those roots.

I have a aeroponic system and i still put an aerator in the bottom of the reservoir - the plants love it! keep us posted on their progress.

ok friends

this is really frustrating. didnt expect results overnight, but i do see more brown spots.

on the smaller plant there are just dark brown spots scattered on the leaves that are yellowish, the sides are curling upwards a bit.

on the other plant it just looks like cloudy brown blotches, i wish i had better definition on the camera.

this is really frustrating, my garden is looking sad. the third pic was my attempt to show how tiny and wrinkled the new leaves are coming in, and the branches attached to the leaves are pretty red....

You're going to need to submerge the roots in oxygenated water. The flow of those aero gardens do not seem good enough. Have you put an air stone in the res?

The plant is obviously not taking up nutrients. Your ph is fine, ec fine everything is fine... but your roots are struggling to take in these nutes. I'm going to ask the other guy who I'm sure suffered the same prob' as you.

yeah if you go back to page 3, i posted some pics of the airstone

i put it in last night at about 6 pm central time. i also made sure to insert it thru that empty seed cup so no unecessary light enters the res.

i did lower the ph about .2. it was at 5.5 this morning.

i do my weekly res flush on saturdays, im home and i can monitor the pH and all that very closely. should i keep my solution where its at (500ppm) or should i think about uppping it this week?

I just loked at the pic's... the roots don't look too healthy. Can you raise the level of the res' so that it covers the roots? Up to around an inch below the net pots?

Also block all light from getting into the res'.

ill get you some root pics in a couple hours, i go home for lunch in 2.5 hrs.

some of them look pretty dingy, but its mostly because of the dirt still left on the roots from the transplant.

but i do know that some of them are a little beige. felt them last night, not slimy tho. theres a couple plants that were never in soil so you can compare the 2.

and yes, i can raise the water level.

they have a fill to line and it sits bascially where that one pic shows. so i have some room to work with.

im salty, and confused.

never grown aero before. i went to my local hyrdo shop trying to get the trio of hydro nutes by FoxFarm.

the store doesnt carry FF, only advanced nutrients. The guy told me to get Vitaboost Pro (1-1-2) and Iguana Juice (4-3-6).

I finally found and Advanced Nutrient Feeding Schedule ( the hydro guy wrote instructins on the bottle and said to do what i would do with FF ) but i just found an actual one from AN. it does not mention either one of those prodcuts. But it also says things on the site like top off with a nute solution, not just water.

The suggested temp seems to be higher than most systems for thes nutes, they say 72 is ideal for res. also it stresses do not have roots sitting in standing water. I wouldnt say the water in the aero is standing, but it doesnt have a current.


im concerned that these nutes are fucking my shit up. Ive never used them and no one on this forum has made mention of them. this is the link to the feeding chart Advanced Nutrients. theres a link to open the pdf file on that page.



What do you think about all that? should i be sticking with these nutes or can i make the fox farm switch?

Nutes are nutes... i doubt your problem is the nutes... so this is a conversion.

This may be why your roots are struggling... you have put the plant through a major transition. Roots in soil are narurally thicker than in hydro'... i believe this is because they have to push through a denser medium.

You still need to get the level of the res' about an inch below the bottom of the pots. It's not working as an aeroponic unit, so convert it into a dwc. This will allow much more oxygen to the roots.

Do your roots have many root hairs?

yeah they have tons of root hairs .

i knew the transplant would be tough. hydro to soil is out of the question because the roots are very thin and it takes too much energy to push thru soil. but thick soil roots i figured would be just fine going into water. They dont have to work as hard to get what they need.

but the root hairs are pretty insane, its almost like a cargo net for some. ill have those pics up around noon, central time. so check back.

im going to dig up some black construction paper and hold the roots against that , so you can get a a clear idea of what we are dealing with here.

im glad its not the nutes. i was sitting here in my office salty at that hydro guy!

An overview on the conversion:

4 Seeds were in my regular soil grow room. They were in 4" pots. Planted 11/8. I got the aerogarden and set it up on 11/14, the following day i rinsed the roots and did all that. **they were still really young seedlings and the roots were not that extensive

So from 11/15 on ( about a week from seed) they were in the aerogarden. For the first 5 days they were in pHed water and under the hydro guys suggestion, foliar fed 1/4 strength nutes. Then i went to a nute solution in the res.

i just used bagseed, from here in the midwest (shitty stuff like 30/8th). i wanted to try this thing out and see how it does. I also put in 2 additonal seeds on 11/15 of quality bud seeds. Dont know the strain, but they were just some i collected from the stuff i regularly buy(around here 350/oz)

So of 6 plants 4 are converts and 2 are pure aeros. Same stuff is happening to all the plants, some not as bad as others.
