Small brown/purplish spots/blotches on fan leaves in 2nd week flower. Growing indoors in soil with FF nutes and soil under SF4000 light. Spots look faded purplish on underside of leaf…
Leaves come and go. How about pics of the full plant?
Are those off the bottom of the plant? Your plant looks healthy.
Those leaves coming from top, middle and bottom of plant…
I’ll take a stab. Likely lock out caused by low root zone pH. Slurry test, and check run off. Looks like a calcium issue. Top and middle typical signs. Top to bottom effected areas suggests its systemic. not due to a lack of nutrients, but more than likely an uptake issue. 6.5-6.8 is appropriate for flower. The dip could just be from the soil being acidic, or over use of nutrients leading to build up.

Using FF nutes and soil, have you performed a Sledgehammer flush? I haven’t used FF in years, but it is highly recommended every few weeks as salts buildup at the root zone. This could kinda go hand in hand with @Low
