my month old plant has brownish patches- any ideas?

Need more info about your grow. Fert. Watering schedule. Etc....

4 inches tall in 3 gallon pot. Ive fertilzed with 1/2 tsp “fish shit” fertilzer and 1/2 tsp “roots organic uprising grow” per quart of water about once a week. and plain water in between if dry a few inches down. Its in a bathroom so kind of humid and at 65 degrees average. 200 watt led light about 6 inches away. seems to be spreading but slowly. one leaf was touching the soil

Your starting to over fertilize. Just plain water for the next few feedings.

thank you i appreciate it

Way too strong of nutes

Cut in half
