Problem?

Everything looks good, its a bit of a weak light there for the seedlings but they don't need much anyway and since you will be transplanting you can just burry any stretch that the plants decide to do. Looks like a good selection of strains. They are looking healthy. You don't specify the type of soil ur using, but if coco 5.5 is ok, but if in soil then u wanna bump that up to 6.5 When using nutes use a reduced ammount comparing to what you would use for photodependent strains, so, less than the recomended ammount in the nutrient label. Let the plants substrate cycle between wet and dry. Stay lit growmie, looks like ur gonna have a tentfull on ur hands, good luck.
