Here's a picture of my plant, it's an autoflowering lemon skunk. planted it roughly 10 days ago. I noticed slight odd coloring this morning and it's gotten a little worse. I've flushed the reservoir thinking it's maybe nute burn but maybe someone else can help me out. It's mostly with the leaf on the left, it's showing darker colors at the tip of the leaf and spots near middle

temperature 20 - 25 C
humidity constant 20% never seen it go anywhere else, maybe my meter broken
got a fan running on it
used aerogarden nute tab (small one) 3 days ago and have flushed the water out and added fresh distilled water cause i thought maybe nute burn

I don't know anything about aerogarden or their nutes but she looks pretty young for nutrients - I betcha' your instinct was right.

it's been over 12 hours since i've changed the res on the water, without adding any nutes. She's not holding herself up. Anyone know what's going on

Looks like nute burn to me. Wait until your baby is like 3 inches high to use any nutes in areo, and I'd only use a few drops at first. Then when it shows slight sings of deficiency, then ramp it up

Did you guys notice the darker colors of the plant? She's having trouble holding herself up.

Is the dark colors nute burn too?

could my plant be having issues because of the low humidity? it's only 20% which I find kind of low, anyone have any tip and low cost tips to increase the humidity

Not holding herself up sounds like a air circulation issue to me. It looks like her stem is covered from the wind, so she isnt gonna get wind, making it harder for herself to grow a strong stem.

any reasoning for the spots appearing on her leaves? Also, when i meant not holding herself up I didn't mean by the stem, but actually by the stem of the leaves, the leaves are drooping

Oh. Are the leaves really thick and firm and droopy or limp and lifeless and droopy?

OVERWATERING = Thick firm to the touch leaves and droopyness
UNDERWATERING = Limp, lifeless droopy leaves.

I have no idea about the spots, i have no aerogarden experience. Sorry man.

Drooping leaves are typically a sign of either over watering or under watering. (Only problem is, when they start drooping from over watering it is typically too late to save them unless you are on it like CPR) :)

The very slight yellowing is a tough one.

Maybe a very slight nute burn, or, the plant is having difficulties taking in nutes (Nitrogen) due to being over watered.

What kind of lighting are you using?

While it is true that Cannabis plants produce hormones to stiffen their stalks as a result of wind, it is important to not cause the air to move faster than 14 feet per second, as the gas exchange shuts down. (Kinda like sticking your head out of the window of a car moving at a hundred miles an hour, very hard to breath.

Of course, this plant is barely a seedling? Not ready yet for producing such hormones.

I believe the problem atm is low humidity, try using the bottom of a plastic water bottle to cover it for a day or so. After that ween it off the little dome slowly. Also, you'll not want to use nutes till the 4th set of leaves.

What's the pH of your water? If you're using distilled it's usually neutral at 7.0, Drop it down to 5.8.

I got an airstone in my reservoir so I am not too sure how I can get my plants overwatered using hydroponic system with airstone.
I am using 3 26w 7500k CFL Bulbs and the 3 bulbs on the aerogarden which are about 4700k CFL

I took the risk of starting without a pH meter, I did however order one and am still waiting for it.

So the plant is continue to grow, she's actually had a lot of progress. One of her newer leaves has red-ish spots (the leaf closest to the camera) I am hoping it is just nute burn. How do you think my plant is doing recovery wise?
