Pic 1 is of a seedling that is probably dead – pic 2 is of a different seedling that may be experiencing the start of what seedling 1 succumbed to
Watered every 3 days, kept on heat mats, 9-12k lux light for 13 hours
The symptoms are leaves that drain of color until they turn to a crispy grey – the greying advances from the tips of the leaves to the base
Any insight would be appreciated! For now I’m going to do a foliar application of fungicide but it doesn’t immediately appear fungal to me
