The rust spots on the leaves are getting worse. I flushed twice and fed with a bit of extra runoff, but a day later and the curling burnt ends look like nute burn. Any thoughts would be great!

if you flushed and it got worse it means it is not a nue burn. it looks to me like a big nute def. the fisrt 2 pics looks like a heavy potassium deficiency, the third a lack of phosphorus and in all of them i see nitrogen def. in my experience under qbs, like yours mars ts, plants need more k than under hps or cobs. to solve this i would feed her with some bloom fert (like n.p.k. 2.2.4) and a strong pk (like 13/14). but go easy with them the first time and rise a bit every time.

Led light cause more absorbiment of micronutrient , you have to give them some calmag to let them do the photosintesis correctly ( the purpling of leaves on top)and re integrate the soil with some base nuts in low ammounts.

Did you add dolomite lime to your soil before you planted?

Looks like You grow under led? Purpling leaves are giving it away. Leds require a lot more nutrients because the lights are so bright. Looks like your low on some cal mag , in my opinion. What ppm are you feeding ?Try upping your nutes.
