Re: Sureves' First Grow(Indoor Cabinet Soil) 2011--Bag Seed
Doc, in the very limited time I have been on this site, I have learned that you are incredibly knowledgeable about growing Mary Jane.
However, I'm 98% sure I didn't overwater. In fact, my previous problems had more to do with UNDERwatering. You see, I didn't realize I needed to put in enough water to make some run out. Prior to me joining this site, I had been using a spray bottle and just really getting the tops wet.
I checked the plants today, and they have some brown spots. It looks like the problem is with the older leaves. Unbeknowest to me, my thermometer I had in there (I have a remote sensor that reports back to a home station that is on my desk) malfunctioned, and the temps in there are currently in the high 80s. I think it was even hotter yesterday - could the yellow leaves with brown spots (and a few dead leaves, I will upload pictures) be due to heat stress?
It was recommended to me to use more CFLs (I had two lights in my cab before; I now have 7), and since then I noticed the temps seemed to be higher. I need to work on getting more airflow into the cab - the chill mat that I thought was perfect isn't working well enough.
I'm very interested in this tea idea; however, I know almost nothing about compost tea. Can you give me some more details on what to buy?
Of course, I've read that pH monitoring is very important. Why do you view it as a negative aspect? Just curious.
Thanks for your help, Doc.
Ah....underwatering will also make for poor roots....either way that's what that plant looks like to me....a root issue.
The compost/worm tea is very important in soil. Soil should be alive with microbes and beneficial fungi. Plants in soil work hard at growing roots, so they prefer to have their meals catered by microbes....which is how God designed plants to grow.
Compost tea is a microbial tea and helps make soil healthy and alive. There are several ways of getting this....try garden shops or a hydro shop. If that doesn't yield any leads, you can always buy online.
I'm using a tea called, "Nature's Own." Not too expensive, but worth it's weight in gold.
pH monitoring: aye yi yi.
In hydro, pH is everything...nothing is more important.
However, that's not the case in soil.....not at all. First of all, most potting soil is already pH balanced to begin with. It's also a powerful buffer, meaning that you can add all kinds of water at various pH, both low and high, and the soil will neutralize the acid or base, as the case may be, and the pH in the soil stays right where it's supposed to be.
Adding pH down (phosphoric acid) will indeed lower the pH of your water....but it won't overcome the buffering effect of the soil, so there's no point in adding it. In fact, it will actually harm your plants because phosphoric acid kills the microbial life AND upsets the balance of available nutrients to the plant.
A large container, IE 3 gallons or more, of quality potting soil needs no pHing. If you use some compost tea, you're in even better shape, because the microbes adjust pH on the fly all the time. That's what they do. When they're munching on a rock, they might get down to a pH of 2 or 3 in order to ionize that calcium.....but when munching on a piece of bat poop, they might self adjust their pH to 7.4 in order to deal with the acidic nature of bat poop.
They are your friends. They do all the feeding. Keep them happy and you'll have some high quality smoke.
There's a lot of mis-information and outright bad information on pot-forums when it comes to growing in soil. I believe the bad info comes from hydro growers, who have influenced newer, inexperienced soil growers.
I say stuff like this all the time and am often met with resistance....but if you talk to people who have taken my advice I think you'll find that they're usually happy they did.
I also have grown plants that are fairly healthy from time to time, so I can back up my words with OK results......
I haven't checked or paid any attention to pH in a long, long time.
