Also I’m using RO water. Added calmag in last water. Will add again in next to see what happens. Looks like possibly calcium and magnesium/manganese deficiency. Plant on far right may need nitrogen and calmag because of the stretch this far into flower with grow dots nitrogen pretty much most likely depleted? was thinking of making a foliage spray tomorrow to see if it can assist with the issue. Thinking of the timeline and the transition of the grow dots and me using RO water I’m having a deficiency and not a lockout or burn.
