Here's an update...day 18

Pic 1 is the slowest growing plant, the leaves are longer skinnier and darker than all of the other ones, the brown spots have been there for about a week. Anyone know what this is/was? Will it get better or just get on with healthy growth?

Pic 2 is very healthy. Anything to worry about with the 4th finger on the leaf on the left???

Pic 3 is also healthy, growing wide, not too tall yet.

Pic 4 is the biggest plant, a couple sets of 7 finger leaves, big and bushy, this may be the mango kush seed.

Pic 5 is another healthy one, leavesa re curling under a little bit, actually getting better from the ice pop incident, and it also has a leaf with 4 fingers...WTF??

Should I be worried about the 4 finger thing?
