Some plant problems- with pictures

:hippy:So.. my plants arn't looking very healthy, lots of yellowing leaves, and are having leaves dying regularly. Some leaves are curling inward too.. There about.. 3 or 4 months old and are still VERY short - probly due to not moving the light up enough.. There still on 24hr light and one of them is already covered in bud sites, far more mature than all the others, so i want to make sure he's doing okay.
So, i just got back from Moe.Down and my roomie was supposed to be taking care of my plants, but i came back yesterday and they were all wilting and super dry! I was so mad!! But there fulling out again, dont think it did too much damage, but could all this leaf stuff have to do with not enough water?

And should i snip off all the yellowing leaves? I take the brown ones off, but should i snip them on the plant with the buds? It would probly open up more light, which would be good, but i dunno what to do. So.. someone help! Thanks so much!
peace!

Some of could be too much light.I would have them on 12/12 by now.

Yeah, i'm thinking its time to make them flower.. one is already trying so hard! lol.
should i snip off yellowing leaves though? open up more light? or would it harm the plant if i cut too many?

Light? Wrong.

Do not start to flower them yet. That problem is a SEVERE pH imbalance or toxic salt buildup- either way, the treatment is the same.

Make a solution of plain tap water, you may add Clearex if you like, or a little Soil Syrup, with the pH adjusted to 6.8.

Flush your pots THROROUGHLY with this. You should use water equivalent to 3 times the volume of the pot.

Now make up a watering solution of a complete fert with micronutrients at about half the strength recommended on the bottle. Adjust to pH 6.8 and water with this.

If that's peat soil, repot into a slightly larger container with a nice light soil that is NOT peat- the compost mix in the link in my sig is ideal for nursing sick plants back to health.

Okay.. so i gave them a good flush. I dont have pH measuring stuff.. i really should have invested in some last time you told me thats what was wrong.. but i'm assuming a plain tap flush was better than nothing. and i gave them some fish emulision (its the only fert i have..) I'm pretty sure it's got all that micronutient goodness.
When should i start them on a 12/12 cycle? They've been growing FOREVER! and there still super short.. but i'm okay with that. And how is it that one of them is covered in buds already? there still on 24hr light and have been this whole time! i just dont understand.. thanks so much for all the help!

Did you ever invest in a good soil?
Is that peat?
Until you fix your dirt, you're going to have the same problem, and flowering a sickly plant is just a recipe for disaster.

ruderalis??? will go into flowering without 12/12 ?

No.. its not peat. Its 'organic' crap from miricle grow.. lol.
Its time to make my babies happy.. =]
So.. just peat soil? Should i use something fancy for this time of growing cycle? Something thats not TOO expensive.. lol
Stinky, your the best. What would home grown pot be without you? Probly not very good...
:P

nonono NO peat. Peat is bad. The low pH will cause almost identical symptoms to what you are seeing.

So if that isn't the problem, you have toxic salt issues.

Have you tested your runoff yet? Check the pH of your runoff, and flush well. Adjust to 6.8 if you find any problems.

ohh.. ok. so i dont need to change the soil?
And where and how much is a pH tester?

Doesn't miracle grow have nitrogen and other things in the soil already on time release? Have you poisoned it?

If it is indeed the peat causing this issue. You can simply add lime to the mix to help neutralize the alkaline levels. I used to add peat to my soil mix, and about a cup of lime to help balance the PH. But to be honest, it makes more sense to just not use peat. I used because thats what bog used. And Bog also said to add lime to neutralize soil PH, but is the peat really that beneficial? NO its not so I just stopped using it! Peat helps retain water by the way, the exact opposite of adding perlite. so if your needing to add perlite to help drainage. Then you dont need to add peat to the mix. I think peat is better used out doors where water retention is a n issue. laterz..
