New Grower Overwatered or something else?

Hey everyone!

So I am currently in my first autoflower grow. I am in a 4x4 tent with a 500w ChilLED light kit and 260 XL QB.

I am using autopots 3.9 Gallon pots with kind soil topped with coco loco.

I am currently on day 24 of my grow. I have 2 Forgotten Cookies and 2 Creme De La Creme going.

I was hand watering with naturally Ph’d water until day 17ish and then turned on the reservoir. It seems that ever since I turned on the reservoir the growth of the FC has slowed down quite a bit but the creme doesn’t seem to bothered by it.

This is a picture from last night (day 23)

I turned off the reservoir today to see if maybe the roots were overwhelmed with the water or they are just starting to grow into the soil.

Anyone have any idea what it could be?

Too much nitrogen?

Too much nitrogen?

It’s a possibility. The roots may be growing into the Kind Soil and getting used to it?

I'm not real sure. I'm a coco grower, So I don't have many issues like that, because I control everything that goes into my medium.
I know that dark leaves that claw downwards are generally a sign of too much nitrogen, though.
At 24 days, a healthy plant should have some pretty long roots, So it should have already "gotten used to" the Kind soil. What's the NPK of that stuff, anyway?
Oh... @Waira knows wayyy more than I do, btw.

... the top of the soil looks very dry, BTW,... get the res' open and going again,... the slow down is, in part, because she's in bloom now.... not sure how much stretch this strain is known for? Also, KindSoil might not have been up to snuff, we've seen pretty mixed results here, even during official testing,... a lot of PK shortages noted as well,... Given her size, something wasn't quite right from the start,... keep in mind that smaller plants don't have the deeper extensive root system either, so uptakes of the goods in this "super soil" may not have been good either,...
I don't recommend mixing a true amended "water only" soil like this with pure coco ( nothing for nutrients at all) on top, they are two very different mediums, needing different things and treatments.... Coco is a specialty all it's own, a host of do's and don't's when using it alone,... likely is why she had a poor start,... And since it's organic based, you should be using an inoculat booster of some kind to keep the microbes population stout, they are the real workers here, breaking down and cycling nutes in forms the plants can take up,.....
In any case, you should be monitoring the in-pot pH no matter what,.. you'll need a soil pH probe for this; the Accurate 8 is a good unit for this,....
