I used fox farm trio and bit of calmag but I have seen trying to flush nutrients out cause I seen burn tips on the leaves.Maybe potassium deficiency. Are you feeding them? If so, what? How often, what strength, etc.
I was thinking it could of been nutrient burn or light burns. I wasn't using nutrient for like 2months and was trying to flush out nutrients while keep my led light panthrx2 on the lowest dim.Looks like both if not a lock out on mag or deff. Last pic tiger stripe unusually mag issue.
Thank you for the infoK deficiency, nute burn is just the tips, yours are burned further up and yellowing on edges
