FF Nutes often salt up fast ... ruined many smart pots. Agreed your N is too high ( dark leaf ) .
Run it on 6.3 to 6.5 ph only. Not more , not less.
Run a water only diet to allow plant to consume some of the excess stored.
Beastie can be overload to plants ... I only use it at week 6 - 7 .
Tiger is “ ok “ as a bloom but ...... have found cutting all bottles and powders out and merely
doing a top dress of FFOF to recharge medium was superior .
With a regular water only run for awhile , you are STILL carefully leaching the soil and still breaking up salt. Without adding unnecessary stressors to equation .... Instead of a brutal flush .
Just ph your tap ... it will be fine . Save the stupid distilled water for your steam iron and slacks.
Think about it .... does your lawn , tomatoes, ferns , ivy plants really give a shit what kind of water you give them right out of the hose ?
