To dry or too wet?

hey, I go back after fed her yesterday night and today the leaves goes up (maybe a little bit to up and now they are curly), I notice this morning a lighter cooler inside the older leaves but the veins are still dark green. After some search I suspect a Mag deficiency. I checked my solution PH ans see a bat 7.6. I immediately reduce that and I will wait for the soil to dry a littlest to give her some new ph adjusted water. I post the new picture as update

It looks fine, some plants just grow like this, not all plants have leaves that point up or are held horizontally. Quite often plants with heavy indica genes will be like this for their entire lives and is nothing to worry about, the plant "knows" what it is doing. If it is under watered, the leaf stems will be soft and floppy, which does not seem to be the case. If it is over watering, there is nothing you can do but wait for it to dry out, however the leaves do not curve down like this. But like I said, this downward curve of the leaves can be perfectly normal for some strains. Hope this helps, Organoman.

Look at the stems to tell. If the stems are curved down and weak then it needs water. If the stems are still straight( like in your pictures ) it is something else. I would say over watering lack of oxygen to the roots. Is this picture from the morning or evening. Some strains will sag down like that just before lights out and for a short period after the lights come on.
