It sure looks like K def, to me. Plants are stacking well, otherwise.
Here's the feed situation.
Jacks 3/2 with 1/2g/G MKP and 60ppm of Biomin Calcium. There's also 1ml/G of Mr Fulvic. Very strong stuff, as it seems. EC is about 1.6
I can't recall my ratio before today since I just made changes to the recipes again this morning. My current ratio is 163-71-211-182
Mixed strains in the room, the issues are mostly on the 2 Black Zombies. Plants are in hempys, fed daily. The room is vertical with stacked 315 CMHs.
I doubled the MKP to 1g/G to see you that works out, but other than not getting worse, how would I tell if it was the right course of action? I don't want to overdo it with the MKP especially.
I had a few ideas...
I starting ramping up Ca 2 weeks prior to flip and through transition and their stacking like they never had prior in the 5 years I've been growing. Did the extra stacking make demands for K?
Or..
Maybe the Mr Fulvic is chelating so well that the plants are getting to much of something?
Or...
Maybe I still need more Ca and it's not allowing enough K?
Still learning!
