The orange sport appeared on all 5 of my plants overnight. I attributed those to calcium/magnesium lockout due to the low pH at the roots. I already flushed the medium with higher pH and did some foliar spray with CalMag. The conditions didn’t seem to worsen over the past 24 hours. Any other thoughts on what this may be?
Looks more like something was spilled/sprayed on them, maybe nutrient solution?
A mag deficiency would show as discoloring leaf edges first, calcium spots would not be so well defined around the edges, would fade from green into the spots
You might be right, because I did spray Pesticidal soap & Neem oil mix the night before I’ve used many times b gore and never did see this type of reaction.
