Seeking a bit of advice for my grow...

[Markass]

I was wondering what problem is indicated by the yellowing of leaves near the edges while in the middle and other parts of the leaf it's nice and green. And one more thing...Watering. How much watering is necessary? I've kinda been basing my water schedule on the dryness of my soil. Once it's dry, I pour water covering the surface of soil. Can anyone help me out?

Watering should be done when the soil is dry 1/4 to 1/2" deep. And water it until it comes out the bottom of the pot.

And i would guess nitrogen or mangnesium deficiency.

Well, I've got three growing in a bucket hoping to get at least one female plant and the smaller one is the one turning at the edges of leaves, and the others seem just fine. Would it be affecting the others as well? "And i would guess nitrogen or mangnesium deficiency."

Is it happening from the bottom leaves(older) toward the top(newer growth)? If so it's nutrients

It could definately happen to only one plant. The 3 plants aren't identical they will use varying amounts of nutrients.
