Is it too early to add nutrients to these girls?

Some are doing just fine and others have some signs of deficiency. Yellow spots, wilting leaves. Any advice or suggestions? I'd like to get some nutrients, but I'd like ot make sure they are at a proper age and not too young.

(Blurry pictures below are from my pos phone , but I tried to point out the problem plants.)

Lights: 3x60 watt efficiency bulbs
Water: spring water (which I'm not sure if THAT is the best idea)
Medium: Miracle Gro Coir - With Basic Nutrients. (N, P[SUB]2[/SUB]O[SUB]5[/SUB], K[SUB]2[/SUB]0)
Age: 2 weeks

Thanks!

Because the ph in distilled water is an average of 6.0 to 6.5 . Not just the price, it also dosent have any additives. Im a noob still so correct me if im wrong..
 
bigv1976, any nutrient suggestions? I don't have a local grow hardware/superstore... just a small nursery business and home depot near by.

b18chbr, I can understand the distilled water preference, just because of the whole distilling process that takes away everythin.


Thanks again

If you say so. Distilling is just boiling and all it is removing are all the micro elements like copper boron and iron.

I would go with something like Neptunes Harvest or Jack's Classic. You should be able to find one or the other locally. If you cant anything will work as long as you keep an eye on your plants and dont over do it.

Distilled water is not just boiled water.. Distillation involves boiling the water and then condensing the steam into a clean container.
 
No need to use distilled water with soil plants..they are better off with safe drinking water from the tap, mineral, spring, bottled or drinking water...you don't want sterile water...you want live water with all the organisms and minerals it has, or has had added back...depending on the type of water...distilled and RO are good for hydro, but not so much for soil...soil is dirty...so sterile water is not all that great...anyway, They are too young for nutes...wait til you have 2 sets of serrated leaves...
 
miracle grow might be your problem. i use normal tapwater with liquid oxygen, formulex which is a root stimulator and cocco a & b. then tst ph and us ph upper or down if nessicry
 
What you need to do now, is transplant thoses babies in a bigger pot. :D

I always wait till third weeks for nute, exept for some fish emulsion, at 1/2
 
They look a little small for nutes just yet.

Water and seaweed IMHO (or what ever sea weed extract you use)
