I dont know what to do i have read everything i can but nothing works help anyone??

 

[icmag.is.#1]

I think you may be over watering. dirt should be almost dry before watering again.

Lack of Iron because of to much water?

 

[kushism]

to me the white on the leaves is a sign of magnesium deficiency..

MAGNESIUM (Mg)
leaves yellow and may even turn white while veins remain dark green. Blades die and curl upward. add cal-mag or follow the advice below

Maybe your plants are just mg whores and need a bump with an added 1/8th teaspoon (per gallon) epsom salts, the initial fast fix here.

Hope it helps

well from what i was reading this is what i thought but i have been adding epsom salt for 2 weeks now and nothing

Should be mixing more thin one tablespoon per gal?

 

[CheifnBud2]

hard water puts salts in your soil.

Calcium Chloride locks out magnesium.

plants dont like too much salts or calcium.

 

[Core]

if i where you i just check you soils ph and not the runoff!...then you can rule that out and we can take a look at your Modus Operandus.
coz this ain't a Mag/cal prob!

 

[PBwins]

The PH on the 3 worst are between 6.6 and 6.4 all my plants were planted in the same soil and all are given the same nutrients all with the same water, but about half are doing just fine and the other have have been growing like this.

 

[TheMintMan]

Definitely sulfur or iron deficiency. Regardless of which, you need to make sure the fertilizer you're using has enough of the appropriate micronutrients. Most of the time you don't need to treat a specific micro deficiency because a good general purpose will cover most things...except when you've got a MG hog...but this doesn't look like a magnesium problem to me.

How much of each nutrient are you using with how much water? 1/4 teaspoon each gal

You may just need to increase that a bit.

The PH on the 3 worst are between 6.6 and 6.4...

If your pH drifts above 6.5 an iron deficiency is one of the first things you'll see.

Of epsom salt? No. Never.

 

[PBwins]

well i just ordered some Earth Juice Microblast, so if it is sulfur,iron, or magnesium this this should help right? is there anyone super micronutrient i should try?

 

[TheMintMan]

This is an analysis of what you have: http://agr.wa.gov/PestFert/fertilizers/FertDB/prodinfo.aspx?pname=2067

And this is an example that's closer to what you should have(Fox Farm Tiger Bloom): http://agr.wa.gov/pestFert/Fertilizers/FertDB/prodinfo.aspx?pname=3497

Note that the ferti-lome lacks many important micronutrients. Either get yourself a decent micro additive, or get a better fertilizer.

That should do the trick. Later on down the road if you start noticing a MG deficiency, add a tsp of epsom salt. MG is the micronute that is closest to being a primary. See how things go with that EJ Microblast first though.

 

[tree&leaf]

I agree with TheMintMan, that's a micro nutrient problem.

I'm not familiar with your soil or nutrient, but those numbers are far too high and either lacking sufficient micros or causing them to be locked out. Other observations that are probably contributing -

If you've just repotted, you shouldn't be feeding, let the plant take what it needs, if the problem persists consider changing your soil.

Your feeding frequency is too high for those numbers. Seriously consider getting a better quality mineral nutrient solution with lower NPK values.

Don't let water stand for that amount of time, the evaporation of chlorine is not important unless your water has excessive levels of it. In allowing chlorine to evaporate you're also allowing all the dissolved oxygen to evaporate with it - roots NEED oxygen.

If chlorine is an issue, allow it to stand but bubble it for a few hours before use to replace the dissolved oxygen.

Your ph is fine - it's not the cause or anything to be concerned about.

It's NOT Mg deficiency.

should i be using the Fox Farm Tiger Bloom or the grow big? im not to the flowering stage yet.

 

[TheMintMan]

Ah, yes, the Grow Big for veg. For some reason I thought you had already initiated flowering. Tiger Bloom for flower...with the EJ microblast should work well. Just don't over-do it. I have a sneaking suspicion that (although rare) since TB has such a large amount of zinc and the microblast has a good amount as well, that you could end up with a zinc toxicity...which is very bad. You would have to use a lot, but I'm just throwing that out there. Like I said it's very very unlikely.

Do a grow journal and let us know how it all goes eh?

 

[PBwins]

Thank you for all of your help, ill be back soon with pics to let you know how it is going

 

[TheMintMan]

Doh! The links I posted above may have been wrong. If they didn't take you to an analysis of the product you have and Fox Farm Tiger Bloom, check them again. They should be correct now. I think the link keeps changing, but if you go to the website and do a search you can find an analysis of almost any brand fertilizer on the market.

 

[Hydro-Soil]

I would stop feeding a Tablespoon of Epsom per gallon, if you still are. That's an awful lot of salt. 1/8th teaspoon per gallon is fine, when you know you have a mag deficiency.

Edit: How are they looking now?

 

[bitpoop21]

What Nutrient's are you using? ferti lome gardeners special 23-18-16
there you go its the ferts

 

[HeadyPete]

yup, ferts and probably lack of micros in that crappy chemmy fert. those are high numbers and very potent, but not complete fert. Everybody nailed it. No mag problem, ph is good.

I recommend Power Blend Pro for ease and results and organics. PBP and molasses for veg and bloom and maybe an extra like Floralicious plus, top max and/or liquid karma to fatten up the buds.
