That "taco" look usually indicates heat stress.... Sometimes heat mixed with hot soil (as in high nutrient enriched soil) will make the leaves fold in that manner as well....

CanGroIt Reviewed by CanGroIt on . What's up with my plant?! It's been 20 days since I planted this one (not counting germination, add 3 days for 23 total with germ) All the stems are a dark purple as you can see, the cotyledon's started yellowing a couple days ago & are not shriveling up & dying... The leaves seem to be healthy, other than the two original serrated leaves, as seen in the picture... within the past 4-5 days leaves started growing out like crazy, so I'm assuming it's in veg now, but it's worrying me because it hasn't grown much height Rating: 5
