I am also a first time grower. using coco with 30% perlite. I am in south Florida so I have an ocean breeze, humidity at 60-80 percent and the heat index is around 85-95 degrees. They were planted two days ago, started poking out of the dirt yesterday, and today is the first time I see them standing except the leaves are curling down. Is this because they’re still growing up or is it overwatering? I gave them 2 liters on the day I potted them. Waterings were a liter each about 4 hours apart. Thinking that the issue is overwatering but I would like to see what you think?
Dead on with the over watering , at that stage they should be getting minimal water like a shot glass full a day. I split it up and do half in the morning and the other half at night.

I agree with the over watering… 
I’m guessing your growing outdoor with that temp so you may have go up a little on the water due to the temperature.

What do you think? A cup of water a day between the two?
From my understanding they are not taking water up through the roots right now, mist them

About 2 tbsp of H20 a day for the 1st week. Dome them to help keep them cozy w/o drenching the medium. If the medium dries sooner, add water.
Once they get going, you’ll want the Coco to stay moist, so nice waterings every day or every other day.

I thought they say it’s ok to water heavier with autos in coco because the risk of salt build up or nute lock etc? Just curious I buffer with cal mag and rinsed my coco before planting I also mixed in a small amount of fox farm ocean forest. I haven’t watered very much because it always feels dampish. I’m on my 4th day today and seeds are starting to come up a tiny bit. I haven’t fed anything since I planted l checked the ppm the meter said 1583 I thought in the first stages of life the ppm should be a lot lower like 300-500 maybe. I’m guessing it’s because I did a cal mag buffer because they say coco lacks calcium
@Myfriendis410 knows more about Coco
I would not do this. You end up with a ‘crappy’ soil, not media. Gotta pick one or the other.
THAT’s why.
Water daily with coco. You do not feed at every watering. Usually it’s F/W/F/W but you hit peak growth and runoff is stable ppm then you can up to F/F/W/F/F/W. Or some other combo. Use cal mag on water only days. Flushing periodically is required to remove sequestered salts.

Thanks for the reply, first grow hopefully things will take off, next grow I will stick to coco might be a lesson learned.
