help for new grower.

[samonz]

If anyone can you guys and gals can
Hi all these are skunk no1 planted on the 16/2/05 in 8inch pots
Under flouros 18/6 temp 70
This started about a week ago and has got worse,
BTW I havnt give them any neutes yet? :friends
Have just given them rain water and a mild spray every couple of days.
Top few inches is dry but when i removed one from its pot the soil underneath was moist and warm.
Roots are also conforming to the shape of the pot, whats a healthy root look like?
HELP!!!!

 

[filimagno]

this is a basic overfertilizing ....the soil is rich or too salty...and u have add much ferts than it needs(use chemicals as i can see from the photo)..or in every way ur soil is gone to acidic...u can try with 2 teaspoon of wood ashes ..it don't sick ur plant for sure!!!

have u read the salinity in the rear of ur soilmix pack??it's around 1200-1300 i suppose.or the soil is added with much nutes than it can takes up!!!

repot only with soil and add only water for 3 times

same trouble here too samonz...
cmon us first timers need a push in the right direction....
growin........

 

[zeppelindood]

i agree with fil... your soil may be "hot" with ferts burning it. Get soil that isn't loaded with ferts and repot to 2 gallon or larger pot.

samonz, here's a few questions at ya:

Are you using preferted soil?

When did you start having problems? From day 1, or is this more recent?
Healthy roots are nice and white.

Are you misting your plants with water? You don't need to mist them, but if you do so it must be done at lights off.

Your plant is also quite stretchy, you should either get your fluoros closer (how far away are they?) to the top of the plant or put her under a MH or Agro bulb.

You are probably overwatering also. A good method to figure out when your plant needs water is to lift the pot, if you feel it light, time to water, if its a bit heavy, wait.

If you give more detailed info it'll be easier for us to give you a hand. Its just guessing without some concrete details :wink:

 

[samonz]

Thank you all so much for the info;
Yes i have misted with the lights on(opps)
I used a general potting compost with perlite and vermiculite.
Thankfully the roots are white
problem started about 5 days ago and from what you say Blue I have over warterd.
Thay are about 2-3cms from the lights.
Ph meter indicates about 7. will try to post pic of meter in soil.Or will get test kit.
Sorry Blue I dont know what perferated soil is!
Zep, Could i get the soil you mention at my local garden centre
Will also chek the salinity Filimango thanks.
Thanks agin you guys. :friends:

 

[samonz]

Do these pics help.
the first measures light

the next is ph

the next is water

he means pre fertalized soil....like miracle grow potting soil. it comes with the fertilizer already mixed in. to me they look burnt by fertilizers. those leaves must feel a little crispy compared to the healthy ones?
1. i would just about let those plants touch the flouros lights. the closer the better.
2. when you mist with your lights on you run the chance of exploding a hot bulb. but under flouros i always mist the fan leaves to keep the stomatas(where the plants breathes) clean and dust free.flouros dont get hot enough to blow up with misting...the hps is another story!
3. it must be getting to much ferts somehow? go down to a walmart or greenhouse and buy soil that doesnt have ferts in it already. buy just plain potting soil. mix alittle perlite in it and repot into say a 10" pot instead of the 8". try not to disturb the roots too much. and just give it water for a while.

 

[massass789]

though the top growth looks fine. ithink if you do what i told you , you will be fine. thers is still healthy groth going on so things aint to bad!

 

[Guest]

massass, I'm not a he, I'm a she, and damn proud :wink:

samonz, your pH is a tad high, but not enough to damage your plant. Cannabis does best with a pH range in soil anywhere from 6.2 - 6.8 tops, depending on the strain. Misting is best done at lights out always, even with fluoros. Did you repot the plant recently? Try doing as suggested by massass, buy yourself some potting soil which doesn't have any fertilizers added, if in doubt ask at the store. Add 20-30% perlite (i've heard not very good things about vermiculite), and repot your plant in that to a larger pot, make sure not to overwater, and it'll probably clear up no problem :smile: Your plant is not in bad shape at all, and you did very well by asking for help as soon as you noticed the problem. Every grow will be a learning experience, and you're starting off just fine

 

[samonz]

Thanks massass I will repot into larger pots and use plain soil.
Can I take away some of the soil from the root system when i repot as it seems a pointless exercise if i add the old soil to the new, or would this shock the plants to much.

 

[Guest]

samonz, you can gently brush away the old soil from the sides and bottom of your root mass, very gently though, and make sure you don't let the roots stay exposed to the light very long :wink:

 

[samonz]

Bluexx thanks; No i didnt repot everything was roses upto sataday last, first i noticed a purple tinge to the leaf but have learned thats normal then the colour change started to happen. Thing is I have just come back from my local garden center non the better as the sales person couldnt tell me which composts had ferts and which didnt. (useless) So will try another later.
Will sort the PH with a kit
What good lady have you heard about V/lite?
Will take more pics when I repot so you can see the roots.
This morning things dont seem to be any worse exept for a few lower leafs shriveling up on 2 of them.

 

[massass789]

i have always misted with the flouros on. if a drop hits the cool bulb nothing happens. is electric shock is your concern then haveing the lights off is pointless also. just unplug. but just dont try to hit the lights .........if a drop hits the bulb you are ok.
the prefert soil will have the amount of ferts in it listed on the bag. it will look like the front of a fert box or container. 20-20-20 or 5-10-5 or whatever.youll notice. or just buy organic soil and its solves the problem with no guess work.

U have some good advice - XBlue is a pro /

http://www.icmag.com/ic/showthread.php?t=4986\

I found this thread very helpfull for a new grower & U will find a LOT of what U need to know to grow world class meds

Your rain water could very well be acidic - start using ROoss water & 8'' pots are not big enough to flower well in -

Roots are the life system for plants - bigger roots- bigger buds


With adding No nuets it's doughtfull u have nuet burn - instead I think U have a deficiency

When in dought - flush it out = use luke warm good pH water & leach the dog out of them - I would then repot into some good 'potting soil' & find a good stand alone ferts - (BOG's thread adresss this well)

They also don't need as much water as your giving it -

If it's not dry - don't apply

After a few weeks plants get the water they need from the roots & misting is not needed - I only do it to create humidity


Good blessings on the rest of your grow

If it's not dry - don't apply

Sounds like you've been talking to a certain someone at Advanced Nutrients, Fred! He's the best isn't he?!?

 

[Harry Gypsna]

ythe problem with vermiulite is that ulike perlite, it holds water and nutrients, and will get waterlogged. Its OK to use a mix of the 2 though! I am curruently experimenting with a layer of vermiculite int he bottom of my pots for sub irrigation as its great for wicking ater up! Id just stick with perlite for nbow though if I were you.

 

[samonz]

thanks

thanks

thanks for all the info people; Have done the repot,see pics





I was recommended John inns No2 for the soil and i used 25% mix of perl/vermiculite.
I then waterd till it ran through the pots and have changed the light system to a 250watt son T.
Also I have pulled off a few damaged leaves.
The result in growth has been amazing the change in light and the fresh mix has give em a great boost.
I am not to sure if the tips of the leafs have ceased to be affected or if the damage will repair.
A local plant doctor and fellow grower looked at the pics I took and concluded that the mix i first used must have been very basic and therfore caused a neute deficiency, hence the new mix from j/inns.
So we will wait and see what happens.













Thanks again yall for the info;
