Looking for any grower feedback on the below, seeing something we have not seen before.
Have a large greenhouse facility in CA. Automated light dep.
Bays of 500+ plants in each bay.
Plants look healthy in propagation, mom appear healthy.
Aprox 3 weeks into flower bud heads appear stunted, leaves closest to buds are yellowed, rest of leaves on plant look healthy but small.
Plant will continue to grow through harvest but buds are very small, leaves are brittle, almost zero trichomes, no smell, not sticky at all.
Maybe 10-20 plants out of 550 exhibit the issue, but increasing number. Plants right next to them are healthy and vigorous, climate is the same, feed is identical (coming from automated fertigator feeding entire bay at a time). Issue crosses strains so its not genetics.
Best guess at this point is infected mom and issue is being spread by cross contamination in propagation (scalpels etc) when taking clones.
Anyone seen anything like this? stumped everyone so far.
Thanks for any feedback.
