I am a new grower, and I am noticing light green/yellowing spots are starting to form on my cannabis seedlings. Leaves are a bit wrinkly.
I germinated 3 Bruce Banner Autoflower seeds 12 days ago, and the last one sprouted 8 days ago. I planted the seeds in jiffy pellets, and then planted them directly into the medium. The idea was to keep the seeds moist in the Jiffy Pellets.
The Promix is amended with 70% Gaia Green 444, and 30% 284.
I have them under 3 full spectrum QGLED grow lights, which are 3 1/2’ above the seedlings.
Humidity has been between 40-60 RH, which has been hard to dial in because I live in a dry climate.
Temps have been between 24-27°C in the day, and between 21-23°C at night.
Was worried about over watering, and so I waited for the medium/jiffy pellets to dry out before watering them yesterday. I made sure to only water a small radius around the seedlings. The water I used was pH to 6.6.
I noticed the light coloured spots on the seedlings throughout their grow, but seems more pronounced in newer growth.
Can anyone tell me what these spots could mean? Is it something to worry about? Can I fix it somehow?
Any help would be appreciated.
