Hi Mojo_Risin,
Best way to know for sure what's wrong whatever the problem is, is to back track every step.
If we keep a log of waterings and feedings or even "events" in the grow when we look back we find what could be wrong faster.
Moving forward I would let it dry a bit more as the leaves look droopy - overwatering? If you point a weak fan to the fabric pots it will help you get through it faster.
When possible flush with PH water with nutes. If you don't have any boosters use a bit more of the bottle with more PK ratio. Additives like B-52, Overdrive, Big Bud would really go a long way though I know AN is expensive they really work well.
