Hello everyone,
This is my first grow. It's original amnesia from seed about 4 weeks old. Growing medium is Biobizz lightmix + Regular flower soil (It was just biobizz lightmix until last week). I didn't add any nutrients yet. First leaves got almost yellow. But top fan leaves look like darker than normal. I keep it under 6400K CFL about 18 hours and 6 hours under the sun. So what's wrong with my seedling? Is it the time to start giving nutrients? I just have Bio Bloom, Bio Grow, Sensi Cal Mag Xtra and Parker Neem Tonic for protection. I appreciate for any comment.
