nute locke up

Is it true that if nute's for a hydrophonic system are mixed togeather that this can cause nute lock up meaning nutes lock togeather rending them no good.Just been watching the grow more buds dvd and the guy in that dvd seems to know what he is doing so i was just wondering is this the case.If you have not seen that dvd yet it is a must see truely ammazeing 300 plants in a 12 foot by 4 foot space budded from about 3 ince tall great if your a dealer of this the greatest plant ever but i couldn't bear to let it leave me.I have no problem with those who grow to sell but surely if your a smoker like me 1 grow and everything could be left till you run out just think how nice that last few ounce would be if cured right great dvd a must see for any aquamist or hydrphonic grower not to say its a waste of time for the soil grower.

Here's a simplified definition of NUTRIONAL LOCKOUT.
Can you imagine sitting a plate before a child at dinner time, with his most favorite food, hot dogs, ketchup and french fries? But also on the plate is a major portion of steamed broccoli, which he is just not fond of and insists on nibbling on. Now imagine telling that child, "you can not eat the hot dog and fries if you do not eat all the broccoli too". NUTRITONAL LOCKOUT is when the child responds with "well then, I just won't eat!"

Most nutes are pH balanced. But after being in your tank for 5 or 6 days, and being eaten from for 5 or 6 days, they become imbalanced. Perhaps you are growing plants that ate all the nitrogen first and just snacked around the iron, magnesium and calcium, or visa versa. The results are discoloration in the leaves, yellowing or rust spots, or curling up of leaf tips. It also becomes apparent when your plants were consuming a gallon or half gallon of water every day, and then suddenly when you check the levels the next day, they did not drink any water at all. This is NUTRITIONAL LOCKOUT. It is almost always due to a pH problem.

You will have to mix up your nutes at some point.....or you won't get the right balance. However, the idea is to never mix the nutes DIRECTLY together.....always have your water as a buffer. An example of good mixing would be to add one set of nutes to the water and mix it up, then to add another set into the water and mix it all together. An example of bad mixing would be to take set one of the nutes, putting it in a bowl, and adding set two to the bowl.....then adding that mixture to the water. Make sense?
