@Pmal027 its still moist on the top 1 inch. I watered it on Sunday night. I am planning to transplant it to a 3 gallon pot. Should i add more perlite? Need your advice. Thanks you guys!
I wouldnt worry to much. It could be from overwatering or heat stress.
So if you are going to do anything it would be to let the top 2 inches of soil dry between waterings.
And maybe move your lights further away or get the rooms temps lower.
