Hun-- did you flush between veg & flower? Some plant strains are very touchy to being over nuted- and are shallow feeders- so if the nutes keep building up, they lock-up.
Depending on the type of Fox Farms soil, it may be too rich- you usually do not feed them until week 4 or 5 of veg in Ocean Forest or Happy frog..... and Happy Frog can have weird pH inconsistencies.
IMO- Flush the plants with just plain old tap water (unless heavily floridated or smells of chlorine- then use filtered/bottled/RO) Once they have drained well- add a couple quarts of your flowering nutes at the levels you'd use for week ONE... and go from there. JMO-- but been there, done that, fixed it.....

There is a 3-pack available of Open Sesame, Cha Ching and Beastie Bloom IF you can find it!
The last 4 Products are used in small quantities and only at specific times during the grow -- so if you know someone who wanted to go in on the 3-pack with ya, it would be worth it!
