Im 2 weeks into flowering and having a couple issues

ebb flow setup
ph is 5.8 if i let it go to 5.4 the plants get yellow tips
GH lucas formula just switched to 8-15 micro-bloom
feeding 4 times a day
12/12
using filtered water

Not really sure what I should do to correct it but the problem started after flowering started. Nothing else has changed.

The biggest plant shows no signs of trouble but 2 smaller plants have this issue.
