My SS and Grand Daddy developed pretty severe K deficency.
I'm not sure wich way to go, add more nutes or flush...some insights needed, thank you...
-Humidity and temps are in the zone, so that is not it.
-Canna Terra Vega in veg, now on AN Connosieur...feeding carefully, below half the reccomended doses.
-third week of flower.
-Soil with some clay, perlite and lime.
-20l pots, SS ran away a bit, 1,2-1,6m high. Grand Daddy normal height around 80cm...
Possible causes for def.:
- I overlimed the soil (battling high Ph from the start wit really low Ph watering). Could too much lime did this?
- Nute burn...but my runoff EC is really low 1-1,2, ph 6.6.-6.8 (lime is doing its job...ph water-in in low 5). I upped EC to a 1.6-1.8 with the last feeding of EC1,5. There were no real change, maybe a bit to the worst, but not much.
- Leaves are dark green, again sign of overfert...and wilting up in a V shape. But no signs of Mg def.
which way to go? Add K or Add nothing/flush?
Thank you for your help.
