Deficiency lockout ? Please help with info

hey everyone. These plants are in 1 gallon of coco, 4 weeks into veg. Feeding r/o water with 2ml calmag 4ml floranova per gallon. Ph at 5.9 going in. The plants are growing slow and yellowing. The coco is staying wet for 4 day’s. What can this be ? Also some curled up leafs . Any info would be appreciated?
I also checked the run off of the water and it’s coming out at 5.5 I tried flushing with 2 gallons of water at 1/2 strength nutes and the ph stays the same . It’s a disaster and I can’t fix it
