I'm having trouble with keeping my seedlings alive and growing I'm new to growing my seedling is 1 week from germination. The stem fell over I added more soil and a mulch layer on top to help keep it moist and moved it about 24 inches from my light I'm using a spider farmer sf1000 dimmed to 40 %. My temps are between 72 and 75f rh 65% I'm using fox farm ocean soil nothing has been added to the soil
Its been 1 month I transplanted to a 1 gallon pot. Why is the plant so short between nodes? And I think I have a potassium problem



77 f and RH 65 %



Looks normal for week 1. How has it developed since?
