Plants Yellow

As you are growing in Coco you can not over water as such. If the pot is sitting in its own run off then you may have issues.. Why did you choose Coco as a medium if you have not researched it? It's not the same as soil or peat mix and needs to be treated in a totally different way. As @roberts said is is hydro in a pot.

Different strains have different tolerance watering. Try giving less water especially in coco coir. Give her time they are resilient and will bounce back

Seeing as that is a similar grow medium to what I use I'd say it's overwatering that casuses the yellowing and droopy keaves. Give it a couple of days without watering (to dry out the soil near the roots) and good luck with the rest of your grow

You can not over water in coco it is not like soil. So unless it is sitting in water that is not a issue. It us Hydro in a potter.

Auf den ersten Blick würde ich sagen: zu viel Wasser.
