What's wrong with one of my girls? =(

400w hps for veg/flwr
miracle gro potting mix mixed w/ 1/3 perlite




My girls are starting to look sick, getting yellowish spots and curling funny on certain leaves. One of them I think is very overwatered but I don't see how, the others don't seem to be affected by it and they get watered just as much. Can anyone tell me what might be wrong? The only thing I've done since the beginning is use a slight amount of dolomite lime to adjust ph in my tap water.

on your second pic, mine are starting to do that a little bit...what does it mean?? (second pic)

I think it is over watering. or too much nutrients, fert. Can't be 100% sure though.

ya i did sum researching on this and most of the answer is over watering, which makes sense for me sense i watered mine yesterday (maybe to much) and mines is slightly starting to look like that

You should check out the growfaq on this site. It's under plant problems in the menu of growfaq. Look up Nitrogen deficiencies and as for pic 2, the only thing I could find was possible ozone damage. check out the pics.

light is too close

If you used regular miraclegro potting mix with continuous release plant food shit its probably a nutrient overdose.
