Any ideas how to fix my problems ?

[qulimax]

Hello ! First of all sorry for my english.So its my second micro grow. I had problems with my first one :
So i started my new one. Everything looked good, but 2 days ago something bad happened to m plants.
Any ideas how to solve this problem ? The lamps are 1x23w 6500k spekter ionizing or w/e it calls, and 2x20w 6500k. The soil is organic with the ph between 5.5-6.5 with 95% of organic something like that. Temperature is around 26 C all the time. I watered with snow water. My soil Ph meter doesnt work, so i cant tell what is it. I didnt fertilized them. They are 21 days old today.Dunno what to tell more....Hope to get answers.

First plants were clearly just very hungry. Your second grow is probably being over-watered a bit. Do the watering by weight of the pot. Fill an empty pot with dry soil and then lift it for comparison. When the pot with the plant gets close to as light as the one with dry soil in it, it's time to water. The plant should be drooping a small amount by this point.

Also, put the water in a basin of some kind, and place the pots in it, and let the water absorb into the pot from the bottom. This is called bottom-watering, and it's the only way to do it right in my opinion. This means the soil above the water line only absorbs as much water as osmosis can allow it to. The speed that this happens depends on what soil you are using. Leave them soaking until the top of the pot is visibly dense. Then pull them out and place them back in the grow cabinet.

I'd also recommend a bit more light. The plants look nice and compact, which is good, but when they get even a little bigger they will be wanting a lot of light. Maybe add one or two more CFLs.

I have more CFl's but they are 2700k spekter. Two days ago, when i got back home, the pots were very light, and i think it's because i forget to water them. Can this be the problem ? And i'm thinking of reconstruction of my pc case :

The brown spots on the plant on the right look like nute burns to me. If you haven't fed your plants at all, maybe a part of the roots hit a "hot spot" in your soil.

Should i cut the damaged leaves ? I think i should transplant them into a big pot like the picture above, and put some dolomite lime. What do you think guys ?

Pure as the driven snow.

Aloha Quilmax .

Do not cut the damaged leaves. Those kids are gonna need all the stored energy and photosynthetic ability that they can get.

When the leaves are of no further use, the kids will drop them painlessly.

You said you were using snow water, yes?

If this is so, you will need to add some CalMag to that water in order to get a meaningful PH reading and to keep from getting those spots on the leaves.

This applys to RO and distilled water as well.

Those spots will multiply, go necrotic, and the plants will die without available Magnesium and Calcium.
Add about a teaspoon per gallon, (about 250 ppm.), of Calmag and shake the jug well to aerate it just before you water.
Or If you keep it in a bucket pour it back and forth between 2 buckets a few times before applying.

"Flat" water can suffocate roots when you bottom water.

You can get away with stagnant water when watering porous growing media from the top as the water will draw air behind it as it drains rapidly.
But, if you bottom water. Aerate the hell out of the water first and remove any left in the tray when you're done.

Ok i transplanted my plants...i hope they will get well soon

Hi,

Your problem makes me feel about "Erwinia Carotovora" especially when reading that :

I watered with snow water.

It's not a good idea, as rain water it can carry pests or bacteriums and it have to be sterilized by boiling before use.

I'm not sure but I think you can't get rid of it, you can just limit the propagation by eliminating the damaged parts of the leaves, renewing and blowing the air 24h/24.

Hope this helps...

Those plants are VERY over watered !

 

[HindukushMaster]

Nute burn or definitely N def, i would also water them a little less they look like there pretty moist from the soil top

 

[qulimax]

Yeah, cause when i transplanted i watered them. But when the problem started the pots were very light. And then i noticed that problem.
I stoped watering the snow water, cause i dont have more. So im going to water my plants with the water from market. I put in some dolomite lime, and i hope it will help.

 

[basstard]

im going to water my plants with the water from market.

Very expensive and produced lots of wastes with plastic bottles. IMO tap water, pH-meter and pH corrector is the best way.

About the problem shown on your second grow I'm sure that's not a nute burn. Your plants don't show any over nutrition sign and you don't fed them yet. As I said it looks like erwinia maybe carried by the snow water and facilitate by heat and humidity conditions, how are your climate parameters ? Do you renew and blow the air 24h/24 ? It's very important your plants breathe day as night and if you don't it causes accumulation and stagnation of the transpired water which could cause diseases.

Another possible cause is water let on the leaves when you watered your plants, it can cause burns with HID bulbs.

 

[qulimax]

My lamps are CFL's. And yeah, the air is blowing 24/24. The water ph meters are very expensive in my countrey, so i'm not planing to buy one. In the future maybe. I think that my plants are getting better cause today the leaves were a bit greener then yesterday

 

[basstard]

today the leaves were a bit greener then yesterday

Good news :smile:

This is a very confusing thread.

This is the main reason why I like plain soil without any nutrients and General Hydroponics Floranova Grow and Bloom.

So simple.

I don't know about anyone else but I literally detest, with a passion, having to come to the boards and ask about deficiencies. It takes forever to find out the right information.

Plain, fluffy soil with perlite and vermiculite added fed with Floranova solved all of that for me. Georgeous, healthy plants.

If you get a chance, I highly recommend switching. Otherwise I would pick one person to listen to and follow only their advice. (PM works well)

Be persistent, pay attention to details and you'll eventually succeed

 

[Weedhound]

Weezard pinned it first with the poor water source. They may be slightly overwatered as well but when I see bowing leaves like that my very first thought would be rootbound. Unless there is no drainage in the bottom I would find it very hard for you to "overwater" in that sea of perlite.

Ps...Do use CalMag for any "store bought" water and invest in a good ph meter. You'll thank me later. I don't think I would be adding lime to ANYTHING unless I could monitor the ph of it.

well i think everything is going well. I topped the left plant. http://img140.imageshack.us/my.php?image=20090205vi9.jpg
