my lower leaves are turning brown and curling up. and a couple of my other leaves are starting to get brown tips. does anyone have any ideas?

Sounds like over fed. Pics would help alot. May be a ph issue.

Why don't people give more information when describing a problem. Things like feed strength, soil or hydro, light, in veg or flower...and at what stage,

Not tryin to knock on ya man...it's just alot easier to solve a problem if we have some information to go by...especially without pics.

Rule of thumb: Leaves curling up...plant is looking for something. Leaves curling down....plant has too much of something.

Drink!

under fed will cause leaves to brown and crisp.
