My second grow COCO

[Clm307]

Sup guys this is my second grow and first in coco so hopefully I can make it through without to many problems , any and all suggestions would be greatly appreciated
3x3x6 tent
260w quantum board( at half power about 3ft away) 24 hr
coco perlite mix (washed and buffered with cal mag twice)
2 peyote WiFis
RH 75%
temp 80f

Germinated by soaking two hours then placing in wet paper towels , then placed in jiffy pellets

Seed broke surface on 6/22
Gave first watering at 6/25 which I thought was a ec of 300 but actually was 1000( due to faulty ec meter )
this went on for the last two days till I got a new meter today . So I don’t know what to do but give a proper diluted dose tomorrow and hope for the best but as of now they look healthy ..like I said I’m new to this but I have done a lot of research. suggestions would be much appreciated

My $.02 is when the plant is that small you don’t need to water until runoff. It is easy to overwater at that stage. I wouldn’t water again under the cup is almost completely dry. Happy grows.

I thought it’s harder to over water coco? I was told to saturate whole media to help with salt buildup?? Is this wrong?

You’re right brotha. Coco needs to stay saturated. I forgot you were in coco. My bad happy grows brotha.

Well with an educated guess on your leaf temps your probably mid to upper KPA range for thier age. They should thrive in those conditions if light, nutrients and watering fall in line

I made a thread here that I feel is a bit more new grower friendly.

VPD (vapor pressure deficit)

Ok i was gonna sit down and write out a whole article but i have been lazy so instead instead I'm going to copy paste because im lazy. This is not my work so let start. You may find this very long but its worth the read. Some may want to skip ahead. I have added here and there to what i feel is...

Also using this free app on my phone so I don't have to use my PC spreadsheet anymore.

Day 8
Watered to runoff about 20%
ph6.2
Ec 450
Run off ec 850?? ....tomorrow I guess I’ll water with the same ec or slightly diluted to try and bring runoff ec back in an acceptable range? Anybody got any thoughts?

Day 9
started to notice slight browning of the tips of 1st pictures seedling
Watered heavy with lower ec to get runoff ec in a closer range ,ph 6.3

Looking great man. I wouldn't worry about anything yet seedlings are temperamental little things. Just make sure they dry out well before watering. In those conditions prob like 4-5 days. The cups will feel like it has nothing but styrofoam. Remember the majority of roots are in peat pellets right now so still have to treat kinda like soil until up potted.

Here is a great article on coco for once you transplant. Easier if you just read then ask questions.
