Teaming with microbes says chemical salts kills the micro organisms we know and love. But you should understand when you add chemical salts a new host of micro organisms suddenly appear that can process chem salts. So you can say that it kills the micro organisms or you could say it doesn't kill...

What type of nutrients do you give them and is it always the same regimen or do you hold some things out for certain reasons? What type of soil is that? How many weeks in flower are you at this point? Have you only been seeing your flowering plants by HPS light and you do not look at them under...

Ok nutrients, even organic nutrients, have a pH value so they buffer the environment in the direction of their pH. When you started out you gave them some bitchin soil it is actually very rich in nutrients + pH buffer so everything was fine. But you mixed other things in with that soil that...

The sad thing is the U.S. Government prefers lobotomy, shock therapy, or numbing people completely out with hard drugs rather than just legalizing marijuana. Those drugs combined with alcohol as medicine are literally forced on those most desperately in need! If marijuana was legal across the...

1/4 cup per gallon at 6% is the safe amount. It should mostly dissipate within 24 hours

Yeah because 5 dollars won't even buy a decent joint these days so what stoner cares about 5 bucks. What a bunch of morons and they think I'm wasting my life.

Yeah it is true excess Nitrogen delays flower and hurts yield through inability to grow roots freely. That's easy to forget if you are of the school less is more.

When the pistils (white hairs) burst out of the bud sites you are in transition and you should taper then stop bloom nutes. Just read the plant. To stop vertical growth you need to use super cropping methods which basically means to pinch, twist, weaken and sometimes physically bend over the...

To help I need to understand the natural temps we are working with. Is your home always cooled to a certain temp? What is the temperature inside your home? Is it possible we can run the light at night and pull in fairly cold air directly from outside through the light hood to help combat heat...

An indoor plant doesn't develop a protective waxy coating on her leaves. So you need to acclimate her to UV-B slowly allowing only a couple or few hours of sunlight per day for about the first week. When you move her into the sunlight full time this needs to be a day where you can keep checking...

I think that it will get twisted around again where we can't grow and they will try to make mj super expensive for everyone. So marijuana prohibition will continue because we are a gentle group of folks not likely to open fire on anyone. Right now I am growing legally 100% but I am betting that...

CXB3590 is separated into bins and colors but we only use a few options. (Not all outlined by any one thread) Here's a DIY of an option: http://rollitup.org/t/diy-with-chilled-pcbs-and-cxb3590.912864/page-2#post-12735060 Here's another thread I read recently...

It looks like it could be Powdery Mildew http://www.growweedeasy.com/white-powdery-mildew It's literally a powdery substance the top layer should brush off and you can watch it fall against the light

When I see green veins with light striping on the leaves my mind goes instant to mg. Did you say your reservoir water is 73F? hmm, frozen water bottles.. The plants look something, wind blown, too hot, too low of humidity.. At work this computer sucks I always tell people I can't see too goodz...

You didn't list ambient temperatures but you mentioned an air conditioner. Attics are too hot and you are already adding more cost by doing rdwc and water chiller. Also no matter how careful I am building a system I typically end up finding a way to have a leak. I think you should setup to use...

Yeah probably root rot we don't water them every afternoon.

Yeah and also depending on reservoir size you should be swapping it out a lot more. But your nutrients say not to use it alone http://1274ym4fbva545shrh1giu44.wpengine.netdna-cdn.com/wp-content/uploads/age-old-grow.pdf

I feel like you need bloom nutrients that's mostly Potassium and pH fluctuations which is likely do the fact that it is gobbling up your buffer i.e. p/k. I am on my computer it is pretty horrible so if your not in flower right now, umm.. oops. Do not use a p/k booster at full strength that can...

Many of us use that much Calcium but it is always at about 5 to 1 ratio with Magnesium. We do in fact use nutrients as buffers in many cases. Basically say you provide your nutrient mix and to start it's a light solution because the plant is little/tender. But she eats up a lot of the Calcium...

Ok I guess using Celsius you will be looking at 1 or 2 degrees above ambient temperature around the tent if done correctly. You don't have an intake fan with a tent it isn't going to disburse very well you need to do all exhaust at the top pulling cool air in passively from below.
