Im not sure.

[lethal purple poison]

If its early in the grow season, well its july 1st(happpy canada day to every one ) I think i burned one of my plants, its not bad, and if i left it i think it woud be fine, the Fan leaves now have a few brown tips, and the the new growth has a brown tips, nothing serious, Would it be better to flush the plants and then mist them with kelp spray to correct the problem or just cut the leaves off and let them go, I was told to do both by a friend but i also herd all you need to do is just trim off the brown edges, wich im not really sure about that, so the best advice would be greatly apreciated, im growing a strain wich is called mighty might(a cross between an indica and a sativa)
Thank you.
