what's wrong with these plants?

Buddhapest said:

I have a few new plants in a bunch of different systems and setups but they all have the same problem. A few of the leaves will yellow at the tips and some will eventually fall off, I check and replace my nutrient solution regularly but the problem persists. does anyone know what this problem is and how I might cure/prevent it?

Using ph up or down is toxic to plants. And will cause lockout.. believe it or not. Get some real good soil and add 2 1/2 tbs of finely granulate dolomite lime per gallon and you will never need to check ph again. The lime stabilizes it throughout your grow. Also, the lime adds calcium and magnesium which marijuana craves.
