Start of week 2 flower today, introducing big bud this week, gave them the full 4ml per litre recommend on the bottles and noted a small mute burn on a few of the leaves but nothing major.
Switch to larger reservoir (25l -> 100l) and added bubbler stone as I'll be keeping the feed over 3/4 feeds, this should help keep the food solution oxygenated and fresher.
Overall the plant is looking very healthy and seemed to transitioned to bloom food v. nicely.
