Thanks in advance for your help. Heres my issue. After switching to flowering nutes (fox farms 2-8-4 tiger bloom) my purple caddilac plant started developing yellow leaves. I weaned it off of the 6-2-2 fert. for a week as it showed signs of flowering. Most of the yellow leaves are fan leaves.
Checked pH (6.4), moisture (midange) combined nutes (normal, midrange). They are about 2 weeks into the flowering stage.
My other plant (sherbet) looks great, and is right next to the cadillac plant. No evidence of bugs, except ladybugs occasionally. I live in San Jose, ca.
Can anyone help? I have done all the tests I can think of. See pic.
