I guess that they are coming out of seedling stage when the start to get tier second set of leaves? not counting the first 2 round ones as leaves, if one has its leaves starting to drop a little and I noticed a little spot on the edge that looked ate away, but it could have came out that way, all others are fine. I'm guessing they are close to 2-maybe 3weeks tops since popping, but there was no light for a week other than a lamp, anyway do you think I should start to feed them now? they are in a seed Jiffy seed and plant starter..so there are little to no nutes..thanks for any help
