Leggy Seedlings From Weak Light

Leggy seedlings with a long pale stem between the soil and the first leaves are the result of light that is too weak or too far away in the first week. An indica should stay short and stocky from day one, so a stretched sprout is a warning sign rather than normal growth. The fix, which is burying the stem up to the cotyledons at transplant and bringing the lamp closer, is explained with photos on https://kushindicaseeds.com. A windowsill almost never provides enough light for this stage.
