All grow mediums have NPK values in them.. this is caused by the natural breakdown of the medium. Most all grow mediums are made from the same things, composted forest materials. Miracle Grow is one of the only grow medium manufacturers that put the NPK values on the front of the bag. The values...

They can get a huge response from curious people looking for a so called "good deal" or popular 'hype' strains from idiots who leave their phone numbers on pot-forums. When they spam many threads at once with their lame lists, it makes it that much harder to get rid of quickly. Admin & Mods try...

What makes you think that because it's only happening to one plant that this is not a molybdenum deficiency? All plants are a little bit different, I wouldn't expect both strains he's running to have the same symptoms, because they are two different strains. Not all strains feed the same... even...

Is this a soil grow? Molybdenum is best absorbed by the roots in soil at pH levels of 6.0 - 7.0... be careful using a pH of less than 6.5 in soil. If this is hydro or a soil less medium, Molybdenum is best absorbed by the roots in hydro & soil less mediums at pH levels of 5.5 - 6.5

If this were true, then hempy buckets would never work... and they work very well. Peat moss has a natural pH of around 3 - 4.5 which is great, if you're growing blueberries, but not if you're growing cannabis... peat moss is not capable of sustaining the life of a cannabis plant all by itself...

Yeah, I'd say that Molybdenum deficiencies are fairly rare to find in cannabis. The pH value is the only thing that can attriubute to this deficiency. Check your pH and amend accordingly.

Let's answer your question, Mike. Overdrive contains.. potassium nitrate, potassium phosphate, magnesium phosphate, magnesium sulfate and ascorbic acid. Ok, lets break it down a little further. Potassium nitrate aka saltpeter is a source of macronutrients nitrogen and potassium. Potassium...

I agree with Dirty.. it appears to be a molybdenum deficiency. The red leaf tips are the giveaway. Molybdenum deficiencies usually occur when phosphorus and sulfur are deficient. Molybdenum helps the plant absorb nitrogen from the air. Greensand lime will fix this problem, so will tomato plant...

Those posts are created by spam bots. Usually, after they are allowed to post things on a site, they will hit every thread on the site at the same time. All that mods can do is delete it when they see it... that's why folks like you guys reporting it to a mod will get the job done faster...

This is true, a pic of the whole plant is important because it shows all of the problem that the plant is experiencing. Different deficiencies affect different parts of the plant in different ways. The pic you showed is a definite iron deficiency... you can tell for sure by the paleness of the...

HPS light makes it hard to tell what color the affected area is on your plant. With the HPS light on, it could be misdiagnosed very easily.

Ok, I see what you're talking about now. Those are leaf anomalies, they are a fairly common occurrence in cannabis plants from seed. It usually only affects the first couple of true leaves, the plant will grow out of it with no problems.

Absolutely. Cannabis pollen may last years if stored properly. Keeping the pollen in the fridge is best.. like Bud Tipps previously stated, but it doesn't have to be kept in a fridge.. it can be kept in a cool, dark place too and still be viable for years. Heat and moisture kills pollen...

What mast crop are you talking about, cannabis does not have a mast crop. Mast is the edible vegetative parts or seeds produced by woody species of plants, like trees and shrubs. A mast crop only pertains to forest nut trees, like acorns or the fruit of the beech tree. Maybe you're talking about...

Looks like your plant has a magnesium deficiency. The green veins, along with the yellowness of the entire surrounding leaf is the giveaway. Also, the discolored leaf tips/edges and the curling leaf edges tells me that this is a magnesium deficiency. Give your plant some Epsom salts, mix at 1...

Grow up Shmuck. You haven't proven anything, except that you're very immature. https://www.facebook.com/RobertConnellClarke http://mjgrowers.com/book_lets_research.htm Ok Shmuck.. scroll down until you get to the "How do fan leaves function" section. You do know how to read , don't you...

You really act like a little kid, Shmuck. It's not TMV, it's HMV.

This is why I said you were an idiot.. look harder. Try looking his name up.

Chuck, you really are an idiot. Apparently you didn't look very hard... perhaps you should google or bing Robert Connell Clarke and see what comes up.. you could learn a lot from guys like him. I've read many studies by Robert C. Clarke, he is the world's foremost Cannabis botanist. His papers...
