These girls have been in a mix of sphagnum moss and perlite and being fed Fox Farm's Grow Big for hydroponics. They have now been in a aeroponic system for a day. Perhaps now they are in the system they will recover but I'm curious to see what you guys think. They are about a month old now. This is my first grow so its been bumpy and they haven't had the best conditions concerning lighting and nutes.

Copy and paste the hydro form. Fill it out completely, and post it here.
You will get some quality answers then. :hippy:
What is your experience level? first timer
What type of hydro set-up are you running? homemade aeroponic
Your Equipment:
A) Type and wattage of lights. CFLs, 26w (100w equivalent), now under two 100w CFL bulbs (400w equivalent each), 6500k
B) Distance from tops? 5 inches
C) Reflector type? (cool tube set-up, bat wing, enclosed reflector, bare bulb...) clip lamp
D) What are the bulb wattages, kelvin ratings, and schedule? 100w, 6500k, 18/6
E) Is there a consistent fresh air supply? yes
F) Do you have an exhaust fan and a circulation fan? yes and yes
G) Size of reservoir? 32 gal
H) What medium if applicable. hydroton clay pebbles, was sphagnum moss and perlite
Your nutrients and water:
I) If using rockwoll for clones or seedlings, did you rinse the cubes well, with properly ph'd water? na/
J) Source of water. (tap or filtered) What's it's ph? 10-stage filtration, 7 ph
K) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. Fox Farm Grow Big for hydroponics, 3-2-6, two tsp per gallon, was feeding about every three to four days when in soiless mix, now its constant
L) What is the ec/ppm of your unadjusted tap (or filtered) water? unknown
M) What is the ec/ppm of your nutrient solution? unknown
N) What is the temperature of your nutrient solution? (reservoir high and low temps) unknown
O) Does your ec/ppm show a rise or fall when you do your daily PPM check? unknown
P) Does the ph fluctuate? stable
Q) Do you foliar feed? If so, with what, how often, and at what time do you
spray? (Just after lights come on, just before they go out...) no
R) How often do you replace reservoir water/nutes? every 2 weeks What does it look like before changes? (clear, foamy, green, brown...) havent done it yet
Your growroom:
S) What size of closet, room or hut? 3'x8'
T) What are the temps and humidity levels while lights are on? ...With lights off? i dont know, i am in a very dry region and it does not feel warm at all in the room, cold actually
U) Have you seen signs of insects in the growroom? no
V) Are the roots long and white, or brown and slimy? long and white
Your strain:
W) What strain are you growing? (Indica dominate or Sativa dom?) bag seed
X) From seeds or clones? seeds
Y) Is this an autoflower strain? unknown
First place I would start is with the ph. It is way too high for hydro!
Another grower on here (oldmac) likes to keep his aero water at around 5.5ph.
I grow in dwc and keep it in between 5.6-5.8.
Get your ph fixed and check it twice daily at first to see how stable it is.
Give this about a week and you should see some change. :thumbsup:
Shit, can't throw ya any rep so this will have to do! :thumbsup:Quote:

Well you should get a ph pen instead of the drops. It's way more accurate.
And an ec/ppm meter too.
Don't know how your budget is, but those would be the first two on the list when growing in hydro.
i got the PH down to an acceptable level i think (see attached pic) and im watching a 6-in-1 meter on ebay....hopefully it doesnt get too expensive
I would be wary of going from soil/soilless into hydro. I have seen that kill several crops for friends. I would try to keep the hydro system sterile, and soilless mediums can often harbor plant pathogens that are kept in check by beneficials, but things can get out of control pretty quick in hydro.
That would lead to root rot, which would lead to physical symptoms like you are seeing there.
If your roots are white and fuzzy then no problem, brown or slimy then you have a problem. :pimp:
