Hello Everyone,
attached below is a picture of one of my seedlings. They're all 2 weeks old, brought up under 2x75W CFL with 6500K, approx. 10 cm above the plants.
Room temps are around 22-24°C, light cycle is 18/6, I water only when the pot feels as light as a dry one, which is about every other day. Started them off in jiffy pots, moved them to pots with CANNA seed soil & perlite, NO added nutrients.
They were doing absolutely great until yesterday, I noticed a yellowing in a couple of seedlings. Today, the first grey blotches appeared all over the leaves. The most developed seedlings seem the most affected.
Is this bleaching? Do they suffer any deficiency? I fear for my babies' lives!
Thanks a lot for your help!
