Slow seedling growth

[Mithweeds420]

My first time growing indoors and im struggling with getting my girls to be happy, this is day 18 and they're way to small, i have been struggling with temps and humidity as i live in a hot and dry climate. Usually day time is 20c to 27c and 50 humidity to 70, night time is 18c and humidity is generally the same.

Smaller seed is 1 week behind

It appears you're in coco......it's too dry and you should be feeding them as well.
If you want fast growth.........start in small containers.
18 days from sprout in coco for a comparison.

I feel like ive been overwatering so ive started using a spray bottle. Should i start giving them small amounts of nutrients?
Also under a 1000w marshydro in a 4x4

If you ask my sis in law she'll say that you're suppose to let the coco dry out because that is what she read on the internet.

If that's just straight coco and perlite you should have had nutes in it before the seeds even sprouted. Otherwise what are they going to eat? The whole pot should be watered well with half strength nutes and not just a little bit around the sprout. Are those autos? Just asking because autos are the only ones I'd start in pots that big.

With coco it's supposed to be watered a few times/day but that would be wasting a lot of water and nutes with babies like that. I use peat based soilless ProMiX HP and water when the pots feel light so I'd be good for 2 weeks at least starting like that. My plants would be a lot further along than those too.

Should maybe read some coco threads to see what experienced the coco-locos are doing. I always check with the pros when I don't know.

Good luck!
