Yellowing Leaves(I have researched)

[privatepile]

Most likely a PH problem as it started before any ferts were added.

I will be getting Ph strips later on so i will check the water i have being using.

How do i check the soil.Add some water and let it run through and then place the strip in to the run off water.

well shit, you learn something new everyday like how using ph adjusters for aquariums is no good for your plants, looks like im making a trip to the hydro store today to buy some overpriced ph up/down

I want to thank every one for there help.

When i have sorted out my plant and i am finished my grow i plan i writing a thread with all the mistakes noobs like me make.

I researched form about a month before i started and still made mistakes.So hopefully i can help other people.

I hope i can save my white widow.I have some Hyndu Kush and someSouth African Durbanx skunk #1 seeds.But they wont be ready n=by xmas the ww might

Ok problem solved.The ph of the water i was using was 7to7.5 that was bottled mineral water.

I have just checked my tap water and it has a ph of 6.5 to 7.

I think the best thing to do is move the plants to the top soil.Give them a diluted 1/6 strength feed and hope for the best.

Is it worth doing this or will the plants die?

I suspect over-watering ... over-watering yellows the plants, and slows growth ... with a seedling that young and small, it shouldn't have to get any water except maybe every 3rd-4th day ... try letting them dry, until they start to droop slightly .. then, water thoroughly, go thru wet/dry cycles ... ( I have bad habit of over-watering, and that's how my seedlings usually look, lol ) good luck ...

Over watering WILL make any ph problems more apparent so Reaper makes a good point there. Plus he and Stinky are both soil pros and believe me.....I'm NOT!

To check soil runoff.....you had it ....water (measure ph) through top.....measure ph of water coming out the bottom. If the issue is ph/burn/overwater and you get it straightened out the plant should do fine from there.

Bramptony....in a pinch you can use distilled white vinegar to lower ph and baking soda to raise it until you can get to your hydro store. Better than your aquarium adjusters.. :thumbsup:

I have changed the plants back to the top soil.

I ran water through the new soil and checked the ph it was at 6.5.

I hope this is ok.

I gave them a very very diluted feed.

I hope they live now.

The water they were using was 7.5.I will not water them until they become dropey and hopefully that will work

pH-wise, you're good to go :thumbsup: ... you hopefully will see some improvement in few days, good luck :jointsmile:

constantly wet / soggy soil will also usually cause the pH of the medium to take a drastic swing towards being more acidic.

I believe they are on the right track when they ppoint to overwatering, I also have had problems with that. A moisture meter is worth it's weight in gold.
