what are u using for mg? 90% of plants do not need mg, versus the contrary popular belief, try this, it wont hurt the plant any plus its dieing, so try it, its worth a shot, first off, if your using floro's, you should be watering when the soil cracks, next, try cuting out the mg, if ur using epsom salt, just cut it out of ur nute regimen, what are you using for ferts? need a lil info on the op. oh yeah, by cuting out the mg, u are allowing ur plant to drop in ph, allowing the plant to start feeding on the nutrients involved in the lower ph scale, try this. ya have nothin to lose, plants do not need mg, u can tell a plant needs mg when, A. the plant will start to burn in between the veins, i.e the composition make up of the leaf, not the stem or the viens, but the leaf itself. will start to dry and crack when touched. if u have any other questions, dont hesitate to send pm, were all here for ur little girls,

hey your ph levels should range anywhere from 6--7.5...unless your skilled enough to control the drops and sudden raises, many are not.
and i do not believe in too much light, photosynthesis is the process which creates energy, a plant cannot create to much energy, energy is then broken down into glucose, a sugary substance the plant thrives on, you cannot have an over energized plant in my opinion.
yes poor drainage is definatly a possibility, i have heard of several techniques to combat this problem, 1: remove plant and soil, layer the bottom with packing peanuts, the kind u get out of boxes shipped to your house, make sure its not the kind that break down under water, layer the bottom of your pot with these, not too many, just a good layer, to wher none of your soil will hit the bottom of the pot, this is a professional green house technique, use at your descretion.
