Several plants developed bright yellow margins in upper leaves during weeks 3-4 of flower. They also have become a paler green and bud development is lagging the others. Their lower leaves (3rd pic) have begun to yellow and develop large brown spots before dying and dropping off. Yikes!!
I flushed with 6.5ph 25ppm rain water three days ago. The runoff tested 6.2ph and 900-1200ppm. Since then one feeding with 6.5ph 265ppm tap water and GH FloraTrio, 2L per plant.
I use the Howweedgrow cheat sheet feed schedule but I skipped CalMag this time.
These plants are 5 gal FFOF and were on Fox Farm trio nutes from about week 5 of Veg. I switched to GH after seeing some symptoms that I thought might be due to salt buildup.
They're under a medicgrow bar6 that's been at 100% since week 3 of flower. Light schedule is 12/12. Temps are 80-83F and 75-78F at night. Humidity is 60-65%.
Wondering if this looks like a lockout of some kind or just simple deficiencies?
