Ah ok.. I have been adding h202 11% at 120mm total every other day. I am hoping to do a res change tomorrow also. The canna recommended ec or ppm seems high don't you think? They recomend total 2.2 but as of next feed it should be 1.6?
H202 is a bit much imo. 11% - 50 - 75mL once a week is enough to keep the res clean, only need to go higher if you have an active infection to kill off, then drop back down again. H2O2 has side effects so you don't want to just blast it continually.
Based on where this thread started, those plants were starving. I'd say the higher EC is appropriate for these nutes.
It’s hard for me to say because I really know nothing about canna.
If this were general hydro 3 part I would say a good rule of thumb would be to start at the same amount same frequency as the grow portion and taper down as you get into flower. In your situation it’s really a total guess. Maybe add 150ppm and see how it reacts?
