If your PH is coming off really low its because your soil is acidic. Raising the PH of your water isn't going to solve your problem. Your pot is too small for that plant. Thats probably the reason why this has occured(salt buildup).

Id flush the soil, then transplant to a 3 gallon pot.

I dont use Canna nutes, but are you using Canna Vega, or Canna Terra Vega?

*Edit: I changed my mind from Iron to Nitrogen. I noticed you have red stems. Thats another sign of Nitrogen def. It will also get locked out at 5.5 or below PH while Iron does fine in that range.

Read this thread to get educated. Hope it helps.

if u scroll to the PH section of the link you provided it looks exactly like whats happening to me. I need to get a PH tester....... I hope i dont have nute lockout......... will flushing correct the PH problem / nute lockout problem ?

Give it a flush with properly ph'd water and then see how the plants looks in a few days. Hopefully that will improve things.
