Sporadic yellow bruise-like spots after nitrogen overload 2 weeks before

This little bitch just DM'd me to complain about my answer, LOL. this isn't lockout and you shouldn't flush, mope. there... is that more direct? flushing is for severe catastrophes in the rootzone. This looks nothing like lockout. you have a bunch of assumptions and non knowledge. you are the one asking for help. not me. if you don't like 1 answer, choose another. don't act like some entitled brat and yell at someone that took time out of their day to pass along a bit of info. there's no specific answer here because not enough information is given and you likely follow a lot of bruh-science, so i'm sure it is self-inflicted madness.

Why you don't listen to RQS or many other marijuana sites.. loaded with bunk info. Best Practices • Feeding: As your plants grow bigger buds, they’ll need more nutrients. this isn't really true and explains why so many have to flush so often, lol. The concentration shouldn't need to change much because the plant will take in proportionally more water. therefore you'd be providing the same grams per week per mass of plant growth. These are rates, not counting stats They give an RH suggestion without pairing it with a temperature (VPD), which is unsophisticated. 16-17C is going to result in autumn colors within a few weeks of flower phase. That's probably not optimal for photosynthesis if it starts refelcting large ranges of red and blue wavelengths. The colors you see are not absorbed by the plant being the underlying reason why this is unlikely a good thing. their ratios arent' too far off surprisingly, but i wouldn't buy into any drastic shifts. numerous studies show these ideas of bombing p or k in flower doesn't actually result in more plant mass nor higher potency. it does show excess fertilizer in runoff which isn't great for the environment or your local water system if you have one. Just self-fellating madness to feel like peopel are doing somethign profound, when the plant does 99% of the work.

I agree with others. Give it the right NPK. something like 4-6-8 and confirm its got a good ammount of secondary macros, eg Mg, S, Ca, It looks like it could use some more Ca and Mg by the looks of it. Good Luck!

ph fluctation or light deficiency of calcium, after flush you have to provide right npk and not overdose again. one / two treatments of calmag would be wise i think.

What are you feeding? Did you switch nutrition to support blooming? Maybe this helps a bit: https://www.royalqueenseeds.com/content/46-the-blooming-phase#best-practices
