Hi All, this is my first grow and I seek thy counsel.
I have a 3 week old youngin’ and her growth has stunted, one of the cotyledon leaves appears to be dying.
medium – coco coir (pre-soaked in water and micronutrient solution)
strain – Diesel Ryder from Joint Dr
water – local mineral (PH unkown)
watering frequency – every 2 days
light – cfl / sunlight (24hrs)
temperature – 20-25c
nutrients – applied for the first time this morning (NPK 8-3-4). 50% strength
humidity – unknown
The seedling was doing fine until wed/thurs when one of the cotyledon leaves started turning yellowish brown. The other cotyledon seems healthy.
The first two serrated leaves are visible but they haven’t grown in the last few days.
the coco may have been too wet for a couple days. I dried it out last night to counter this, but I can’t really say anything has changed.
Nitrogen deficiency (the yellowing). I gave it fertilizer this morning (8-9 hours ago), but no response (yet).
