Curving (not curling or cupping) leaves. Should I panic?

Hey all. For the past week I've notice the leaves on my girl are curving somewhat strangely. Here's a picture of what I'm talking about

View attachment 1086682

It's really weird. I'm not sure if there's something wrong with her. A few weeks ago she almost died from overwatering, but now she's fine.

Growing her in Garden State organic soil, watering with distilled water and FoxFarm Grow Big whenever she's dry. She's about 5 weeks old now (she was stunted from the water trauma) and I'm not sure if this is normal or if I'm doing something wrong.

Thanks all, +rep for answers :joint:

Im assuming your using CFL's since I see a clamp on that pot, so I'll rule out heat stress. Well it might be a pH problem. Do you know your pH? And you said you were over watering. Might be a little too much N, cause I believe plants will twist and curl like that from too much N, and I can see maybe 2-3 browns spots on 1 of your leaves. I would check the pH of your runoff and start from there.


edit: damn I cant spell :(

No, you should never panic, thats how 90% of newer growers make the problem worse by overreacting and turn something little into a huge problem. Doesnt look bad, whats your ph at?

Stress can cause plants to show abnormalities. The overall health of the plant looks fine to me though no major nute burn or anything. Like enjoyit said check your ph just in case it never hurts.

Don't know what the soil ph is at, but I'm using distilled water, so I doubt the water is making anything worse. How do I check/change soil ph?

EDIT: Not sure of the soil ph would be offeither because I've got another in the exact same soil, water and nutes and she's not curving.

I get that from time to time.. I think it's stress-related from ph problems.. it'll grow out of it if you keep the PH in check and give it sufficient nutes.

Just reread your post... I don't think water trauma can cause a plant to be stunted for that long. Your PH must be way off. It happened to me once when I decided to use straight tap water (dechlorinated), and later found out it had a PH of 8. My plants stayed green but they weren't growing for several weeks and the leaves looked like yours.
I believe you have nutrient lockout.

How tall was she before you topped her? (looks like it's topped)

Just because the pH of your water is safe doesnt mean it is when it goes through the soil. You need to check the water coming out of the bottom of the pot. I've seen people use water pH'd at 6.8 and it come out the bottom at 5.0.

Good information, everyone. So now I have a new question: How do I go about changing and checking the ph of the soil istelf?

Just topped her yesterday, I was waiting until she had plenty of new shoots/nodes coming in and a decent amount of space between them.

take your pots run off water and ph test it. Then if its off get 3 times as much water as you have soil and ph it all, then start running the water through, if you dont have a filter or something for your water i suggest you keep approx that much on hand at all times just sitting around in milk jugs or i use old 2 liter mountain dew bottles-i keep 20 of them full and ready to go in case of emergency.

If she almost died from overwatering, then my guess is that you are overwatering it still.

Here's an idea: wait until that cup gets as light as a feather. Forget about ph. Let the soil dry almost completely before you do anything.

Look at it this way: if the leaves are curling now, what difference does it make if you let it wilt a tad before you add anything to the soil?

You'd be surprised how long a MJ plant can go without water.

Also- if you want to test the ph, you are going to have to go to a hydro store or order a thing or two online.

The easiest and most inexpensive way is to purchase a soil ph tester. Stick it the soil, hope the PH is around 7.0


They are cheap and break easily, so buy 2 of 'em! They're about 7 bucks USD apiece.

I'm thinking I may have panicked over nothing. She's looking fine. The curvy ones have straightened out and grown pretty big, so I'm thinking they may have just been taking that weird shape in an effort to get closer to the light. New leaf sets are growing out normal (although some are looking skinnier than the big ones), so I think this was a lot of hubbub over very little if anything.

Thanks for the halp! +rep all around!
