Why are the leaves wavy? Something to be worried a...

If you get yourself ppm/ec meter you would probably find that your water/nutes mixture is too rich. You can see that leaves are dark green. Wavy sometimes is due to over watering. Lower the nutes and water only when pot is dry and light weight

It could have been a ph issue or a genetic trait. My first thought was heat stress but at 72 degrees you wouldn’t or shouldn’t experience that. Anyways good luck on your grow!

Hi there! Looks like you over-watered your plants. Next time try to decrease your amount of water and those wavy leaves are going to step up and shine again! Happy growing!

pH can definitely affect the plant and make it do all kinds of weird things, as others have said. Root rot can, too. Another thing I would mention is that 68% humidity is a bit high. I notice that if my plants are under more humidity than they like, they start to droop a little more. Once you switch these to flower, most recommend 40-50% humidity. Otherwise, your plants look nice and healthy!

If not a pH issue, you may also have magnesium and/or calcium deficiency. Your lights may be a bit close. What kind of light and total actual watts?

twisting leaves like that usually points to issues with pH or some environmental stress (temp, humidity, too close to lights, ect.) might want to check the pH of the water yer giving her, check the environment I have had twisting like this cause a fan was pointing directly on the plant and that caused the twisting. But as long as the new growth is coming in nicely don't make any drastic changes. let her do her thing, less is usually more. Cheers, good luck. 👽

Do you monitor the humidity level? If not them you should🙃 They don’t look overwatered in the pictures, in my opinion a low humidity level is the cause. Basic euipment is a musy. Good luck with your grow.

Its just to much water. Nothing to worry about, yet! You just need to correct that let the soil dry more between watering. Keep track of how much you water them. Weed like more dry than moist conditions.

Happens to almost all of my plants. Be sure to let the soil dry properly at this stage and no more that 1/2 strength of any nutrient line. As the other gents have said your on track with a healthy plant✌️🏻

They do that sometimes, nothing to worry about. Try to raise your lights on temperatures a couple of degrees to 24°C (75F), it will help their development. Other than that, they look fine.

The plants are looking good to me so far especially only the 10-11 days in. I hear you mention heat so I dont know if you've got fans moving things around, that can cause leaves to bend and turn in unusual ways, however I see your day temp at 72 which isn't too high at all, I know they do however recommend at least a 5-10 degree difference at night. I have one of my plants with some unusual leaf patterns and shapes(bending waving etc) and she does seem to be ok, like mentioned below the new growth looks good, just her first few leaves that were off. I think you're so early on that this is just a little quirk that'll get better with time and newer bigger stronger growth. I hope this helps in any small way. Happy growing. Fun sounding strain btw canuk cookies :)

Hi, I'd normally relate it to the pH being off but your stats say its at 6.5 which is fine. One of my plants did this early on but after the new growth they were fine. I wouldn't worry about it as your plants are looking healthy. Keep doing what you're doing. Good growth for week one.
