hi folks, is this calmag deficiency or what? its week 7. i always added 0.2 ec calmag to the solution. why im getting this now? maybe i need more of it. its only in one of the plants.
I am gonna lean on a ph out of line in substrate due to plant is absorbing lots of potassium and phosphorus. Raising ph as it eats. Now causing first signs of lock out for both those nutrients. I don't feel it's cal mag all in your case.
