Foliage dying

[Deft]

Just transplanted into better soil that says its certified organic, somthing called coast of maine (http://www.coastofmaine.com/soils.shtml, cobscook one). The roots are loving it and so were the plants till now, healthy white roots are visible very near the surface if I disturb it a little and the plants are groing fast and recovering from the crappy soil I had them in which was realy slow going and the roots were tiny when I transplanted.

I'll get pics tomorrow when lights go on. Lower leaves on 2 of the plants are dying in patches inside the leaflets, not from the tip up. Only watered once so far as the soil holds water a little too well, the watering was done with a little compost tea and the symptoms starte well after the watering so I dont think it was a bad tea, I used a bunch in one spot on my lawn so I will check that when the sun comes up to see if there are any negative effects.

What could this be? I havent used any ferts aside from the tea and what is in the soil. I'm going to cut long thin holes in the plastic pots to help get air in and water out in case thats the problem, it cant hurt since the soil holds water too well allready.

Reading the description of the Cobscook Blend in the link, it sounds to me like the soil you chose is much too heavy for your plants. Soil that does not drain readily will create lots of problems for Cannabis. Your plants may be drowning.

Sounds like medium stress... we made coast of MAine last year on our outdoor and growth came to a halt. We figured the mix was too dense.

 

[Deft]

it is pretty dense stuff, I looseded up the soil around the roots with a chop stick stuck in where the roots had not grown yet. Going to cut holes too so that may help.. This stuff is realy good for the roos it seems but like you say is very dense, next time will have to add a bunch of perlite.

Here is the pics of the damage, I want to stop this, I've been plagued with problems ever since halfway through my last grow. I think its soil related now since I have not used any chemical ferts, just soil and a tea watering once.

I think I am going to start mixing my own soil, I have had bad luck with 3 different commercialy mixed baged soils allready this grow.. has to stop.

Way, and I mean WAY too hot and not at all suited for a transplant from another bad source of soil.
The main source of ingredient is hen poop, its meant more as a soil booster than an actual medium, basically your last compost tea activated the very dense and hot "medium" and thus cooking began.
That's my story anyhow, I'm judging from the posts and not the pics.

To fix the problem you need to find a peat based medium like Promix, Fafard mix, your looking for a peat based medium with added perlite, a potting soil mix, etc.
To that you add about 30% more perlite, then 2TBS of dolomite lime and your set, include 10% worm casting and your good to go.
Mix it together and moisten with enough water to squeeze a handfull of soil and only get a few drops.

Pop your plant from the containers, shake of the hot soil, drop then into the new containers, try spreading the roots a bit, then water VERY lightly with a little water.

Leave them alone until you see new growth, it will stall them for a week or so, be patient, the castings will cover what they need until the roots take hold, then hit them with a good tea.

I would also suggest a Mychorizal product inside the whole you are transplanting to, it will create a good fungal web and all of the soil working for you while it roots.

I have a 4lb bag of epsoma myco-bacterial goodness, will go out tomorrow and find some peatmoss etc, going to leach it in a big bucket of water since I have had bad ph problems with straight peat before.

I'm well versed in watering and transplanting etc, but have always done outdoor gardening in my rich native soil and not much inside besides verigated spider plants and phalanopsis.. so I am not great at choosing or mixing soil yet because of lack of experience with GOOD soil mixes lol.

Edit: Ohh btw Suby, want to buy a TT AWD?

 

[Deft]

Might add a bit of the best outdoor soil in town, its free and jet black and grows BIG plants. No one will mind as its public land that I lease .

 

[Deft]

Just realized that the single good soil mix I had ever so far inside was Fafard, going to go that route I think, if I can find it again. Good reccomendation.

hate to hijack, but i thought it may be on topic.

i have some young plants in organic soil, however i have made the mistake of watering with chlorinated tap water. i can tell growth is slowed, as i believe most the nutrients are being locked out/killed.

how can i reverse this? will begin bubbling water 24hrs, but is the soil shot, or will it recover after a good feeding?

thanks for replies, and sorry for the jack bud, hope your plants are doing ok.

 

[Deft]

Might want to use the myco-bacterial buddies in a tea next time you water, if you think that you might have killed them with chlorinated water just add more and dont kill them. I'm thinking the chlorine will be gone from the soil by now.

 

[hobosapien]

deft, much obliged, have you made any gains on your end?

those babies lookin any better?

 

[Deft]

Got a bunch of hte same soil I have had great sucess with before, going to use it allong with work castings and perlite and transplant today.

 

[Suby]

Hey deft,

yup indoor plants require a better drained soil mix, using plain peat doesn't cut it, you need a mix of soil and peat and other things.
I don't fit in an Audi TT, i'm 6' 5" and ~200lbs lol, I am biding my time until I can pick up an S4 though, :

Hobosapien you can just bubble water in a 5gallon pail add 2-3 TBS of molasses, a cup of earth worm castings and maybe a little kelp meal or liquid seaweed and bubble it for 48hrs.

Or wait it out they'll come back on their own.

[Deft]

No one around here has worm castings, wtf. Closest place is over an hour away that one person could think of bahh. I'm gonna grow my own soon enough.

 

[Suby]

Yeah worm casting are pricey out here but widely available, I'm working on getting some bins going myself.

Keep us posted.

[Deft]

Looked into getting worms, theres a place next to a fishing spot that sells them that I have been meaning to fish, may aswell get a couple pounds of worms while I am down fishing, can put them in the cooler when I dont catch anything!

what are you buying soil for? why arent you using the native soil with amendments. youll be WAY better off. the soil you have them in now looks like crap sorry to say, those commercial soils are not for growing pot, well foxfarm maybe but that stuffs taxed and still not as good.
you can always mess with a soil to make it fit your needs. even if its crap to start out with, working with the soil over time will give you better results than any store bought soil ever could.

homemade compost or wormcastings are great and will benefit any soil.
