Honestly it depends on how youve been watering. it looks like your on week 3 of flower. If you have a res you should be doing this mix first potassium silicate then you add your bloom nutes then you add molasses then mix it up and always at the end ph down. if your in soil ph is 6.5 and week 3 of flower should be 2.1 ec or like 600-750 ppm. dont just do what the bag or bottles says invest in a meter and your plants will thank you. Also when your res gets low your ppm's will spike and you will have to top off your res with plain water
 
No res I water with a sprayer. I PH at 6.3. I have meters, I didn't check my ppm last time though. What do you think I should do. I just watered the day before last, I don't want to over water but I don't want it to get worse in the meantime. Should I top off with some veg nutes and cal/mag? I'm kinda stumped on this. Never had this before

nah id just let the soil dry out and then next watering just give it plain tap water or id do RO water and cal mag next watering. also put a tray under your plant and check your runoff ph and ppm

yes looks nutrient based. never stop checking for pests always look under your leaves for brown specs

Is it possible that this is lockout??
Dont try to fix your problem by adding 1 thing, just because you think it needs it. you will never know for sure unless you test your water. Your best bet is to lay off the nutes, flush, and then slowly add back a balanced NPK ratio. It could be potassium or it could be phosphorous, but if you try to fix one you can just cause more problems by locking something else out or toxic
 
Actually doesn't look as bad now that I've taken it out from under the LED, seems it always looks worse off. The leaves that already had the most damage are just taking its toll. No saving those I guess. Here's a pic of it today, I may have slowed it.
