What is happening with the leaves, 1 week 3 days old from seed, fed nutrients once at 150ppm
Needs nutrients, and your light may be too close.
It’s a 600w hps light plant is 50cm from light
I used 150ppm week ago for one feed will up to 400 see if it clears up, thank you
What is the growing medium?
Coco and perlite
Yeah that is too close, move it up so it’s about 80 cm above the plants.
Need more nutes and probably calmag if your nutes don’t supply enough of calcium and magnesium.
