I first thought I might be cal def so I used 2 tsp of dolomite lime per gallon in a foliar feeding. Then I tried a foliar feeding of epsom salt at the rate of tsp/ quart. The problem still persists.

You didn't say what the EC reading was.

 

[MicroDude]

Thats because I dont know.

I didn't see you mention how much you specifically feed your plants . I also am using the fox farm group of nutrients.

Are you using exactly the amounts that FoxFarms recommends via that PDF you linked?
If so then that might be your problem. I am running Hydro but I can tell you the amounts they 'recommend' to feed, is waaaaaaay overkill. I would assume that maybe their numbers are also as inflated for soil feedings as they were the hydro.

I am using like half of the amounts they recommend for hydro.

Im a growing noob... but maybe your over feeding, combined with a overly low ph, is causing nute lockout?

 

[generalgrievous]

Salt toxicity...... Over feeding... IMO

Try flushing rather than foliar feeding more salts.

 

[High Country]

No worries, see if you can get hold of one or borrow a friends. Some strains can take high levels of nutes without burning others cannot.

Perhaps try giving them a good flush and reduce the nutes, if they perk back up you know it was nute burn.

Good luck, hopefully some other people may chip in to help.

I have used this schedule on my past grows. I have never had a problem like this. My low run off is a concern of mine but I cant get it to go any higher. I have dolomite in the soil to buffer up but it hasnt shifted the ph run off any. I used to use ph down to get my feeding at 6.5. But after this showed up i have been adding no ph down to try and raise the soil ph level. the first I grew this out it was a seed run. didnt have any problems. didnt check ph back then either. heh

I will give this a try. Dont be to harsh... My pics do look like the symptoms in the sick guide.
I guess you guys also think these DR's are sensitive to the feeding so I will back it off.

Thanks for the feedback. Anybody else feel free to chip in.

 

[MicroDude]

well the problem still persists. I have about 11-30 days... one plant the problems have started to decays the bud on the top. =[ I have only given water since the 23. have a look at these pics see if you still think its over fert.

 

[DIGITALHIPPY]

wow, im sorry for your poor plant. i think it might be magnesium related...

thoes cheap chemical fertalizers dont work very well or fast once the plant is in this state of health.

id sugest microizzal innoculation, organic b vitamins. carbs. maybe a few epsom salts or premium magnesium.

its also been only 8 days... and once its bunrt its burnt, so its not going to lookbetter at that point.

Well I have removed all the crispy leaves this week and they keep showing up. That is why I think it persists. But that is also why I am back because I dont know.

Superthrive? Cab you give up any names? =]

For soil your pH is low and that tiger bloom is a hot fert. So the deal is you're dealing with a little nutrient lockout as a result of your pH problems and your problems with pH are presenting with those little rust colored spots on your leaves.

 

[Darkstarlive]

I'd say you'd be better off giving a good flush with clearex or some other flushing agent and remove all salts from the soil and start over with a clean slate. Just give water until the plants start to put out some new growth. They look fried.

Good Luck...

Well I did pick out the worst plant and leaves. But some of the yellowing is from the natural age of the plant... I think. =] The buds are starting to foxtail. The one plant in the dew bottle is the worst of them all. I think that is because less soil less room for error. Thanks guys.

Those plants do look burnt; different strains will react differently to the same nutrients, even if used in the same quantity.

At what rate did you add dolomite lime to your soil?

Growing in a small container does often mean less room for error, foxtailing MAY be an indication of over-abundance of certain nutrients, for instance without the right AMOUNT of nitrogen the plant has trouble absorbing and using Phosphorus and Potassium, however this may also be genetic.

Personally I'm not a fan of Fox Farms nutrients, though I do like their soil mixes. You're in an all organic soil, FFOF that is, using a chelated partially synthetic nutrient additive; consider switching to organic additives and I really think you'll be glad you did. Organics grow buds every bit as big and dense, but are much more forgiving of errors, whereas growing in organic soil with synthetic fertilizers can actually diminish the effectiveness of the organic matter in your soil to feed your plants as synthetic fertilizers kill microbes which break down nutrients in the soil and feed your plant. Furthermore commercial pH adjustment solutions, like pH up and down also damage, and often kill on contact any microbes in the soil, and microbial activity is crucial to pH in a soil grow . . . it's all part of a mini-ecosystem.

I highly recommend using BioBizz nutrients, but you can mix your own for 1/2 the cost (I just prefer pre-mixed). Also, try switch to Earth Juice natural pH up and Down, they will adjust your pH just as well as hydro adjusters, but won't kill the microherd.

Lots of good stuff here. I want to create that magic soil that requires only water. Until then Ill look into biobizz. =]
