A question from a fellow grower:
I’m growing Jack Herer (seeds) that I bought from ILGM, and I’m having some trouble and would like some advice. I started off growing 2 feminized JH, and 2 regular white widows, all besides one feminized JH died I think because the light was too far away and they grew lanky and just snapped. I repotted the last living plant to a pot with holes. I’m using hydroponic soil - coco coir, and the plant is now 16 days old. The two large first leaves have begun to yellow but are still firm but every day it seems to yellow more. The very tips have started getting darker (not so visible in the pictures below). What I’ve read seems to rule out nitrogen deficiency or high temperatures. I’m using a T5 light that may have been too close because I assumed it wasn’t powerful enough, could this be light bleaching? Is it something else? Nutrients have come mainly from compost but out of fear of rotting the roots I changed the coco coir. Other than that there are egg shells in the growing medium and occasionally I water with water that a pear has soaked in for nutrients since I know it’s unhealthy for a young plant to get too many nutrients. There is cinnamon in the growing medium since I’ve read it to be healthy for roots and leaf production… Humidity is fine. Thoughts?
Spots on leaves are from dust and soil
