The smaller seedling is like that bc it's in a much bigger pot 5gal, there fine it's the flash, i had to prop them up with my bread tie method untill the lay down there roots and gain size, i hate smart pots until your seedlings gain size, dont know if i like this pre mix used to makeing my own, but at least they wont be potbound, use a 600w viperspecta 2 cycle for veg only they have upgraded the light and lowerd the price so i bought another bc i have a 6×6 tent and you can daisy chain them together doubling my grow space, there a good veg light but not to good of a bloom light bc not enough red i think they fixed this, anyway it is a 2 cycle viperspecta 600w led reflector series at $149 it blows Mars hydro out of water for bloom i have a California light works bloom booster cob, surprisingly a very good veg light for the price 100.000 hours and a 3 year warranty daisy chain included, i payed i think $225 for the first one now there a 150 bucks, have had no problem with light since i bought it, would prefer a black dog but you do what you can with what you have.
