imo u have a Ca def ( if u dnt see any bugs). this chart shows which nutrients are taken in at any given ph.
hydro on the left. u can see that yr plant cant uptake Ca if ph never drops below 5.9 or so.
may i suggest setting yr ph to 5.6 to start. naturally yr ph will rise. once it rises to 6.3, drop it back down to 5.6. this way yr plants will be able to intake all necessary nutrients during the swing. it looks like the wild thing has Ca in it so i might try lowering ph 1st before adding cal-mag+ supplement. peace
