Coco Coir Seedling Questions

Horsefunklestarted grow question 2 years ago
Hello I would like to know if it's possible to over compact coco coir as I kept pushing it down when I filled pots and if it's the reason one of my seedlings cotyledon leaves are droopy. When do I first add nutrients to the water? Germinated and potted 2 days ago sprayed 3 times.

I grow in coco. No need to compact it. It will do that on its own. In coco it needs to always stay wet. Your ph needs to be 5.8 going in 5.8 comming out in run off. If not you will experience lock out, and deficiency in about a week if that plant will suffer. Your first leaves nearly store the plants energy for first week to 2 of growth. Long enough for roots to acclimate. At day 7 to 10 add first nutrition very light dosing. Always use a cal mag with coco. I feed every other morning in coco after I set my ph. Then splash ph water on coco to maintain wetness till the next feed. Your ph will be the key to your grow in coco and maintaining wet coco. Coco grow is hydro in a potter or bag. No dry time period. Feel free to PM me if you need more assistance after selecting my answer. 🌱

Yes, you want the perfect density—- not too loose not too compact. And just mist water for now

Cotyledons drooping down is perfectly normal, their only job is to protect the growing tip as it pushes through the soil. After this the cotyledons have no further bearing on the plants life and they are actually not leaves in the true sense. They droop down so that the first set of true leaves get full exposure to light and the whole cycle of life can begin. The cotyledons don't actually store the energy they need for the first few days of growth, this energy comes from the seeds' endosperm and can be likened to the yolk of an egg, which then forms part of the root system as the plant grows. Otherwise, what robert wrote about pH and when to start feeding is good advice. Hope this helps, Organoman.
