Beginner who needs help

Help I am a new grower with a problem. I have a 1500 watt LED, 2X2X4 grow tent, 3 gal breathable pots with intake and exhaust set up. I am using fox farm fertilizer. The issue I have is my blue haze plant is yellow on the tips and has rust spots. I have a purple haze plant in the tent also with no issues.

can I bring this plant back to life ?? Help

Didn’t I just see this plant in another post? If so, try to keep it to one post. Posting the same thread multiple times just clogs up the board and makes it difficult for people with knowledge to find your’ post and help you out.
