Brown spots, red stems?
Posted 30 May 2010 - 09:30 PM
A picture of the whole plant
The red stem area
The yellow spots on both leaves
The yellowing and red veins
And finally the main growth (yay)

I am doing the same sort of thing, simple cfls now, and I have become really successful, my girl is now 2 months old and is flowering beautifully!
Anyway, it looks like your plants suffering from nutrition block-- from either the ph in your water, or over fertilization from the miracle grow. I had the same issues, and it ended up being over fertilization. Make sure you check the ph in your water also, you can do that simply by using ph strips for a pool. if its above 6.5 then you need to lower it. An easy way of doing that is adding a tiny amount of white cider vinegar. Stir it around, a few drops or so in 2 cups full and then retest with a strip. The vinegar will not harm your plants because its a natural compound that will break down eventually. If you think that this might be because of over watering, then cut down on it and only water your plants when the top of the soil gets crust and when you stick your finger at least an inch or two down in the soil and its still dry.
if its true that the soil had too much fertilizer, you may need to re-transplant to a better soil, but thats if its absolutely necessary.
I hope some of this information helped you! happy growing!

If the soil doesn't have them, you should check your pH levels as the previous poster said. You want your soil and water pH to be between 6.5 and 6.8. It is better to be a little higher than 6.5 than to be a little lower. To test your soil pH, when you next water your plants, let a little runoff come out the drainholes, then grab a test sample of the runoff and see what the pH is. It is just a rough estimate of the soil pH but it is good enough to see if your pH is really high or really low.

Also can I test the pH of the soil by taking a bit of the soil and mixing it with water then testing it? This would allow me to check the pH much sooner since I watered it recently.... If I found a pH imbalance would it be better to instantly try to fix the problem or wait until the plant actually needs watering again to do it....?

The ferts in your soil are tim e release and will make the PH fluctuate.
As for fixing it, it will depend on the outcome of the test. But since you have to wait to water to test, anything that means adding more water can be done right away without worry of overwatering. You can give a plant 10 gallons of water and it won't overwater. But if you water 2 times a day with 1 liter it will be overwatered in no time. It's not how much but how often that leads to overwatering.

i had the exact same issue with basic miracle grow potting soil, and unfortunately i didnt read the fine lines about the time release nutrients in the soil. It killed two of my plants, and one of my plants survived it and is still flowering and is lovely.
Fox farm ocean forest is suchhh a great product, definitely get some if you can afford it. I am for my next grow

If you decide to feed it only give 1/4 or 1/2 strength at first and slowly build up to full strength. I would give it a week or 2 to adjust to its new soil before you feed, though.
And I'm not sure about the lights since I don't know what the levels were at or are at now.

How many watts are you using? I would give it full light; the plant "knows" when it has to build root mass. Keep the bulbs an inch or two from the plant. Water when the soil is dry an inch below the surface, or when the plant feels light in weight. It's better to underwater than overwater.
The fertilizer you have is for blooming, but in 2 - 3 weeks you could give it 1/4 strength fertilizer and then work up from there.

I had 3 lights, I turned two off so that the plant would promote root growth. Now that I can see that there are new signs of growth should I turn the other two back on...?
Yes, you can turn them back on. I think that in order to promote root growth you need to give them more dark time, not just less light. So, if you were giving 24 hours light you would cut down to 18 light/6 dark to promote root growth. I could be wrong about that, but in any case I still think you should turn your other lights back on.

It took me 13 minutes to type my previous post. But I agreed with you, Antigen!
Two answers are better than none!
