Friday is fert day. I use Miracle Gro tomato food -- it's 20-20-20, and Baby luvs it so far. She's indoors, fluro 24/0, 8wks old, fert 1x per wk and leach w/ water 1x per wk.
What about Epsom Salts? Lit says this increases magnesium and sulphur, and I want her to be healthy as possible and maybe just enhance her feeding with it once to see how it goes.
Anyone use Epsom salts? Results?

You're right, it'll increase the magnesium but you only want to add it when you need it. If the leaves turn up, thats a sign of magnesium deficiency. If you're plant is healthy, don't touch it... don't fix what isn't broken. Too much magnesium will cause a nutrient lockout for another important nute.

when everyone says turns up .. are you talking about the edges of the leaves? ie the leaf turns into like a trough ...

Doobious

Exactly. The edges of the leaves turn up and in to the center of the leaf. When this happens, there are a couple possibilities to pinpoint the problem - it's not always a mag. deficiency. It could be that your pot is not draining sufficiently. If a plant is sitting in stagnant moisture (meaning the nutes aren't going through the holes on the bottom of the pot) this curlage will happen.
