Just looking for advice

About 9 days into germination. The smaller is Sensi seeds Skunk#1 the larger is questionable.
Using Coco. temp is 74°-79°f.
Grow area is 70°f. humidity fluctuates between 17 and 33.
No nutrients.
Anyway I was wondering why they might look yellow.
Root system looks REALLY nice.
Any feedback is appreciated.

Time to give them some food. Yellowing like that is usually due to lack of nitrogen, particularly early in the grow. And since you have not given nutes yet, we know that is not the problem. Feed with a very mild N based fertilizer and I bet you see results within 48 hours.

Bro you have to feed the plants from day one with hydro as there is nothing in the medium.

Becuz ur using coco and not giving nutes is why ur yellowing. Coco has no nutes in it like other soils/soil-less. Start them on 1/4 strength nutes. Get them sum nitrogen nd ur yellowing will stop.

I wasn't sure if I should give them anything for the germination period.
I have Botanicare CNS17 for coco.
I'll start right away.
Thanks again.

Thanks all. I will start using my Botanicare CNS17 immediately.

When do U think I should transfer into pots?

I would say abt a week or so . U want the plant to have a stable enough root system to transplant safely. When u transplant them use solo cups or 1 gallon pots and gradually work ur way up to ur final pot.

I just grew the skunk #1
it really goes yellow fast in the flower. Of course the fan leaves start off first, about 3-4 weeks in, followed by the rest of the leaves. Just so you know.

Thanks for info!

Well I'm wondering would a 200 watt cfl dual spec and two 35 watt cfl blue spec and two 45 watt cfl red spec be enough to grow two plants in small closet?
