Nute burn or deficiency

some tip burn for sure.

have you checked for mites? i see lots of white dots. you'll need a scope or a loupe, not just your eyeballs.

if anything (other than nute burn), it kinda looks like Mg deficiency. do you have any epsom salts just in case? 1 gram per gallon should clear it up. but i would do the flush first and go from there.

I have been giving them a cal/mag supplement, I do have Epsom salts so if they don’t improve after a flush I’ll give it a go,
 
UPDATE, Flushed for 24 hours in ph water, then added nutes at 280ppm,
Tip burn seems to have stopped but woke to this,,,,F6B72730-2C7F-4E5B-BA44-1D53C4FE29CE.jpegB2C0CEB5-0DB9-4ED7-98EA-AEAF1EA22095.jpeg4998F7A3-D8AB-45EE-968B-9B55CAF1103C.pngAC9219B0-AD1E-44BE-B8A5-B9DE6B89D4F9.png

Did you figure out what the new problem was?

Yes, I rechecked the roots and there was some slight browning/ gunk, so a root issue,,,
Treated with liquid oxygen and started using Pythoff, they made a good recovery until 3 weeks of flower,,Leaves all started dying off and stopped growing,,
