These is a Road runner . Entering her 2nd week of flower. This yellowing started pretty much when she entered flower. Her sister is right behind her beginning to show same signs. Fed her 2 days ago in case it was deficiencies. Ph runoff was 6.3. Her leaves perked right up but still not going back to green. What do I do? Growing in tropic batmix using biobizz nutes with ecothrive charge. Help pls guys.
