Ive supplemented undergrowth with some T8 tubes but here's the pics

Leafs seem to start yellowing from veins outward then leaf edges start curling upward and eventually the whole leaf turns brown and all shrivled upward everything seems to be from vein to tip all help is very appreciated as this is my first time encountering a problem I have never seen thanks

By the way the big fan leaf in pic one is an older leaf that did experience some nutrient burn early on hence the burnt tips and outer edges
