It's an outdoor grow, maybe 2 months into flowering (I'd guess roughly 1 month to go, nice healthy buds already formed, but still quite white and the calyxes in particular look quite unripe still).
For most of its life it was looking rather healthy. I do believe I overfertilized it > a month ago and upon showing signs (burnt/curled leaves) I flushed it and it seemed to recover within a few days. About 3-4 weeks later the leaves started to twist and shortly after the tips started burning again. At that point I had not trimmed it and actually figured they might be twisting/dying because of a lack of airflow (it was quite bushy), and upon inspection all of the dying/twisting leaves were actually blocking buds so I cut them all off. Well if anything now I feel like I've overtrimmed it, yet just 24 hours after the second trimming (the first was a week ago roughly) it's still showing signs of fert burn, specifically the browning/'burning' of the tips. Like I said I haven't given it any fertilization for at least a month, is is possible some are locked in there and I just need to flush it REALLY well or could something else be wrong? Sorry I don't have a camera or I'd post some pics.

I would think it odd for such to show up again (you had said the condition was reduced initially after flushing) 3 or so weeks afterwards with no new nutrients added (no extended release, either synthetic pellets or blood/bone meal, correct?). Type in symptoms on Google and see if you find anything else that could be causing it.
Also check what micronutrient deficiencies look like in cannabis and see if you get a close match... also keep in mind what ones you have added in your fertilizer(s) and soil amendments. If you think you might have something, you can then look for university extension resources local to your area to see what they say about nutrient issues in your soil types.
