Help please!

Anyone know what this could be? It's only on one plant. Growing in soil, strain is Connie Chung. It almost looks like it was fried by the bulb but it is on the middle of the plant not the top plus the hood is air cooled. Suggestions?

what are you feeding them?

had the same problem , on 7 of my plants as soon as i switched nutrients was useing heavy 16 never again . my advice is to run a gallon of water throught it ASAP what i did that will flush the nutrients out , feed them only water for a week and then switch back to nutrients . different brand may have a nutrient blockage, its a great start , outher then that only thing ive seen hope this helps . the prob will go away slightly but new leaves will nott have it

During veg they were getting foxfarm nutrients. during flowering I gave them a mix of foxfarm, some organic tea from a vortex brewer, and they were topped off once with supersoil. They are about a week or 2 from finishing so I guess I will just flush with water and wait. Didn't know if I should remove these brown leaves or leave them on.

i left mine on , the brown leaves only cut them off if you know 100 % sure that leave will die, it will more then likly recover will still have the brown in it, . rember thats what the big fan leaves do soak up bad stuff and help fight stuff off,
