You may have given to much nitrogen for to long into flower causing dark leaves, the curling ones are from heat stress and the bending over ones are from the light.

Week 2: One of the plants still doesn't look good + other beginner questions :)
Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

leaves pointing up
I moved my girls outdoors today. I watered her with plain pH water. I saw the leaves pointing up. I thought it was something good until I did some research and saw where it was caused by light stress. is this true? new grower. what happens if the soil is on the plant?

Why are some leaves curling strangely?
Hello everyone, the problems begin unfortunately. Why are some leaves curling strangely? I have not given any nourishment, the temperature and humidity are constant, will it be a problem of PH or EC? Thank you in advance.

Hello fellow growers :D thx a lot Firstly, is the reason why my plants (especially cookies) are very slightly curling/folding at the ends of the leaves because the LED is too powerful?(Reason to be worried?) Secondly, should I start adding nutrients? Just 1/4 of Bio-grow for now?
