Leaves Turning Brown 1st week of bloom

i would guess that "bloom nutes formula" wasn't as good as advertised. probably too much p or k. i see your other question posted with 3 more pictures, but leaf symptoms are not discrete. That's usually what gets blasted in a "bloom" formula not based in science. node spacing looks fairly leggy at the top, so i'm a bit skeptical about light being the cause. 24/0 is only wise if it is required to give good amounts of DLI, i.e. if you have a weak light it can be a net-positive compared to 18h and 3/4ths the DLI. Might be teh cause of the tacoing, but the health of the leaves seem nutrition-related because it's not just the top leaves from being hammered by photons.

My guess would be either being on 24hr light schedule, so no rest time. To high an amount of nutes. Or the defoliation earlier in the week.

Light is burning it. Can see the edges off the leaves are all pointing upwards.
