Ethos mandarin cookies v3 x cherry berry, flower day 30
Growing in FFHF, following the fox farm schedule (dirty dozen + kelp me + wholly mackerel)
240w kingbrite qb (3000k+3500k w/ IR on and UV on)
pH around 6.4-6.6 each watering
Runoff pH ~6.5 last feeding

Major yellowing on fan leaf tips with red/brown spots... Then the tips eventually turn crispy and brown. Any ideas what's going on and what I should do to fix this?
