need help with clones please (pic)

Hi all, I just bought 10 clones supposedly white widow. They are a couple weeks old and for some reason the larger leaves look like this (see pic) also you cant see it in the picture but there is a blueish tint towards the end of the leaves. Any help would be very much appreciated these are my only hope of an outdoor crop this year, thanks

Plants on last leg any help would be great please

are you feeding them, are you feeding them too much what are you growing in soil hydro is it just the lower leaves how is the new growth. ive had leaves look like that from mag. dif. and over nute and thrips

I Would Not Get Crazy With Fert. Get Some Insta -green From Your Local Hydro Store. Follow Directions On Bottle. Get Some Super Thrive To. A Little Goes A Long Way. Use Insta Green Until They Look Good. Make Sure That When You Water It Drains Good. What Kind Of Lite Do U Have?

1000 MH, Thanks alot for the help, they pulled through whatever it was and are doing great now thanks again!! Happy Smoking
