Can you diagnose this? Purple Leaves on White Widow, Leaves sides curling up, anyone?

[THContent]

Ok, well basically I noticed that my plants are a little curled upwards on the first set of leaves, it doesn't look like anything major, but still worried unless I know it is normal or from heat stress (transpiration). The one thing that I did notice when I lift the leaves up is purplish tinge under side of the leaves, while the top looks nice and green and see new growth every few hours, just wondering if it is from the White Widow strain that has coloration to the leaves or what, can anyone give a diagnosis to this, or whould I just continue with everything as planned in my grow log? Here are a few pics:



Purple underside:








Curling leaf sides, have turned heat down, currently at 75 Degrees vs 88:








Other than that, the leaves look perfectly normal and are doing great, they have a nice green color, no discoloration other than the underside of the leaves which is purple, not sure what it is exactly and the stem appears to be purple under the light.

Not a heat issue. Have you given her nutrients at all? Or are they in a pre-fertilized soil mix?

The tint on the undersides of the leaves is not abnormal. Where did you get the seeds?

Other than slight overwatering, they look fine to me. :jointsmile:

Have you been monitoring temp. constantly? Maybe she is getting a little cold at night.

I have used this in the past to state a plant is female when I see this. Time will tell, nothing looks wrong to me. Let the poor thing grow and don't kill with kindness.

I got em from Nirvana, the undersides on both are purplish, and leave edges are kinda going upward, have not given nutes yet, I am using FF (Fox Farms Ocean Forest Organic mix)

I expected the purple to be normal, but the leaves and a couple yellowish tinges, the weird thing with the yellow is that they are not on the first set of leaves and on the top, makes me wonder if its just genetics, since they are feminized..

Temps sometimes do go up to 84 at night, but most of the time maintained around 77-81.

Here is what I am talking about, as far as the yellowishness:





I thought being this early on, how could I have a nute deficiency? But I guess it is possible potassium related? The yellowish is kinda more light green than anything, I will just keep an eye on it and see what happens, if they get yellowerish I will do 1/4 nutes. I prolly have been overwatering a bit, the soil drys out so damn quick lol.
