Calmag deficiency or Nutrient lockout caused by Pk excess ?
Maskedcucumberstarted grow question a year ago
Flo+44. Probably I didn't remove Pk fast enough (left it for more than 19 days, should have left it for 15). So I reduced the nutes from 1.15 to 0.70 now, hoping to avoid the lockout... Thx !

Honestly your plant is bulking and wants the pk right now badly. Buds will likely suffer, and lose a lot of foliage by keeping nutrition present till it is done bulking anyway.

The only thing I see is excessive nitrogen......P/K is exactly what she wants now.
High P/K levels do not cause lock-out, incorrect pH does.

Magnesium deficiency? How to cure it?Is this a sign of magnesium deficiency (my other plant has similar spots)? If so, I've read online (on the Canna nutes website) that I should spray the leaves with Epsom Salt (2% solution): is this correct? Any other suggestions? Thanks in advance
