My 5 Females May Be Dying!

So some of my plants leaves have started turning purple-ish lately, and I'm wondering what could be causing this. If you can't tell from the pictures, some of the leaves are just curling up and dying.

Any idea what could cause this?

Purpling is caused by an accumulation of anthocyanin pigments; causes an overall dark green color with a purple, red, or blue tint, and is the common sign of phosphate deficiency. Some phosphate deficiency during flowering is normal, though not too much should be tolerated.

I'm no pro, but I'd say you have a phosphorus defiency...possibly a nitrogen defiency too, but consumption of nitrogen from the fan leaves during the last phase of flowering is normal.

DId you bonsai parts of your plant? looks odd

Probably a pH problem, most the soil has the nutes in it, the pH is just too high or low for good absorption. check out this page, read it thoroughly and check out the pics for each kind of def./overdose...but pH is the main cause of def. not because they are lacking the nutrient in the soil, just pH off.

I found it really informing!
