Two sisters, one healthy, the other? What's happening?

[oudenos76]

Hi all guys,

any feedback on the below would be welcome.

Quick recap of the situation.

Strain: RQS Purplematic (Autoflowering CBD strain: Click here for details)
Location: southern europe
Medium: CellMax universal soil mix
Both germinated directly in the pot, sprouted the very same day, 11 days ago
2 fabric pots - one is 5 liter, the other 20 liter
In the very same fabric pots (same model, 5/20, other pots) i'm very succesfully growing 2x RQS Haze auto
Weather so far quite good, a couple of light rain, avg tempo around 25C
Both in full sunlight from dawn till sunset.
Watered both the same way once every 2 days
Gave some Terra nutes for vegetative growing maybe once or twice

Basically, you can see the problem by the pictures... one of the two "sisters" looks quite healty to me, or at least looks the same of the other two hazes that became healty and satisfactory plants last month. The other... quite small... but most importantly, "bad looking" leafs and "crispy"... kind of "dry"... even if she got the same things of the other.

Any idea how to mitigate and/or correct that and if this is serious, what to expect?

Thanks!

That one in question looks like a lil heat stress.. Maybe put her in a more shaded area till she grows a few more nodes and leaves.... Hows the drainage for that plant?
