Did i get the right lime? pic provided

[GalacticGardner]

Hi im having some issues with my 13 day old big mac's and am trying to narrow down the problem and wondered whether i bought the right lime. This is Soil Doctor garden lime brand. I have added a picture of the ingredients and a picture of one of my babies. I have four plants all with the same problem and its getting worse. I had only been feeding my plants water up until yesterday when i gave them some nutrients in the hope that would remedy my problem, it hasn't so im thinking it's something in my soiless mix or the water.
I would be grateful if anyone had any http://www.icmag.com/ic/picture.php?albumid=8027&pictureid=143361input. You can check out my gallery to see the problem I'm having with my plants.

I would say no.. I'm sure its dolomite lime, but the ratios for Ca:Mg are off. I think you want it to be like 2:1. So if you have 20% Ca, you have 10% Mg

Are you letting the water settle so the chlorine and such are gone?

 

[GalacticGardner]

No i haven't been letting the water settle. How long should i let the water settle?
I did think the ratios were off but didn't pay it much mind, do you think the ratios being off could be causing me the problems?
Thank you both for your responses.

heres a pic of one of plants showing what looks to me like nutrient burn but i could be totally wrong.

Looking like nute burn, or possibly a pH issue. Have you checked your pH of everything? (Soil, feeding water, and run off?)

 

[GalacticGardner]

I don't have a PH tester so no i haven't tested it. Could the ratios of lime being off cause nute burn like that do you think?

order this shit, its powderized not pulverized and its in the right ratios http://www.hhydro.com/cgi-bin/hhydro/HH00255.html?id=ay8t3aP8 its cheap to

I would check the water pH so you know for sure..

It looks really wet..

What are/did you feed...

Lime is a radical thing to do as pH isn't a real problem in organic soil..

What are your plans as to what style you are going to use..

Thanks for the responses, really appreciated.

I'm growing these plants in a soil-less mix of Premier peat moss, perlite, worm castings and what i thought was the right lime. I had them under a a couple of 23 watt cfls and everything was rosey, but then i saw signs of the discoloration and the plants seemed to have stunted in growth rate. I then moved them under my 600 watt hps thinking the light was inadequate. I had only been feeding the plants water, so was surprised to see what looked like nutrient burn. One thing i will say is i changed from store bought water to tap water, so that could very well be the issue. Do you have any recommendations for a ph tester? I'm really on a tight budget so the cheaper the better for me.
The nutrients I'm going to be using are the earth juice grow bloom & catalyst.
I may try switching back to only giving them well water rather than from my tap and see if that brings about any kind of change.

If it's normal water don't bother..

Soil less? Well I don't know what to say because organic soil is about the soil biology..
Feeding the plants through the microbes with materials that are considered natural.

If you have a coffee bean grinder try taking some rice and coffee with a little sugar and grind it fine..

Lightly "powder" the soil surface and then get some health soil from outside some natural place and also "powder" the soil..

This isn't all you are going to do but this won't hurt nothing..

One thing also that can happen when watering leaves, the water can turn into magnifying glasses and burn the leaves themselves. I've seen it happen to alot of my moms house plants before I told her not to water them when the sun was highest.

As to the water settling, any water I give to my plants sits out 24-48 hours with the cap off so the chlorine can leave. I don't want to kill any helpful bacteria in my organic soil mix.

Going from a couple of 23 watt cfls to 600 watt hps is a big change... If the plant wasn't stretching out too much I wouldn't say that the light was inadequate. Remember to listen to your ladies... and less is more sometimes.. Just my 2 cents... Hope she recovers nicely.

Oyster shell powder and/or limestone is my preferred choice.

Others will disagree.

OK GG,

First, you got the wrong lime. You have Calcitic Limestone when you should have Dolomite Limestone. I made the same exact mistake as the bags are identical except for the back panel you have in the picture...

Don't panic, go back to where you got that lime and check for the right stuff and get the dolomite- use the calcitic lime on your lawn and garden- it's cheap enough! There may be no problems throughout your grow, however, with the calcite but it does lack the proper ratio of Cal to Mag...

See my post on the Virtues of Dolomite Lime.

Hopefully, you let your soil 'cook' for a month or two moistened in a heavy duty black garbage bag so the earthworm castings (EWCs) and lime could start breaking down.

Tiny plants don't need nutes yet!!! The EWCs are the nutes!!! No nutes until the cotydons are yellow!!!

What you are seeing is almost certainly the result of overwatering. Think moist but not bone dry. Roots need air!

OR you've simply overnuted them- hopefully they will outgrow this damage...

Good luck!

Thanks everyone for the help & suggestions. I think the problem is under control, I'm still entirely sure of the cause, but the burn has ceased and a couple of the hopefully girls are starting to grow up once again. I will be going lighter on the water from now on.
Thank you again everyone that responded, most helpful.
